Definitions
- the invention relates generally to methods for modulating the immune system of mammals and more particularly to methods of modulating the immune system using compositions comprising histamine derivatives.
- Histamine is a small molecule that has been shown to have a significant role in the immune response process in mammals. However, its ubiquitous effects on many cells that have receptors for histamine limits its possible immunotherapeutic use. Histamine derivatives that are tissue directed or effect specific would significantly aid in determining the role of histamine in immune modulation and produce valuable immunotherapeutics.
- Histamine can substantially modulate models of immune responses in mammals, particularly models of delayed hypersensitivity and T and B cell functions. Histamine is synthesized during different phases of response to antigen and is able directly or indirectly to effect further responses to antigen. It is possible that the concentration of histamine in tissue during inflammation and immune response can modify the function of a number of lymphoid cells. Although these effects may be substantial, the direct effect on single cell types in a mixture of cells cannot be determined unless the agonists are effect or cell specific. Ubiquitous effects of agonists on all cells that have receptors for histamine would limit any immunotherapeutic use of histamine. See Khan, et al., Clin Immunol. Rev. (1985) 4:1 Melmon. et al.. Am. J.
- Histamine is an autacoid as are catecholamines. prostaglandins and some peptides. e.g., bradykinin and probably lymphokines.
- Autacoids differ from hormones in that they are made at their local sites of action and they can be made in a variety of tissues. Autacoids play an important role in mediating inflammation..- During inflammation, certain events may occur which include: protein denaturation. lowering of local pH, release of "new peptides" and lysosomal enzymes, and the like. Such events create a setting in which the immune system should not overreact to the new products. Yet, despite the ability of inflammation to generate likely immunogens, the inflammatory process usually is not accompanied or followed by grossly abnormal immune responses. Autacoids appear to somehow modulate this response.
- Autacoids affect natural suppressor cells, T cell subsets and B cells during various stages of immunity.
- Receptors for autacoids are non-randomly distributed (in number and affinity for agonist) on cells that carry out immune functions.
- Precursor B cells do not appear to have histamine and catecholamine receptors, while B cells committed to produce antibodies do.
- T suppressor (T s ) cells modulate the CAMP responses of T helper (Tj-) and T cytolitic (T c ) cells to histamine. Mitogens alter responsiveness of these cells to histamine.
- biologic response is inhibitory (e.g., reduced release of antibody from B cells: inhibition of lymphokine release or lysis of target cells by T effector cells and inhibition of release of histamine from mast cells); in others the response enhances immune function (e.g., enhanced suppression by natural suppressor and T s cells or T helper (T ⁇ ) cell proliferation.
- inhibitory e.g., reduced release of antibody from B cells: inhibition of lymphokine release or lysis of target cells by T effector cells and inhibition of release of histamine from mast cells
- T ⁇ T helper
- the autacoids seem to be enhancing selected early events in immune response (e.g., enhanced suppressor function) while inhibiting later phases of phenotypic manifestations (e.g., release of lymphokines or antibodies) of immunity.
- the natural suppressor cells appear briefly during the early maturation of lymphoid tissue but can be induced in adults by total lymphoid irradiation.
- the cells have the unique feature of inhibiting the antigen- specific cytolytic arm of alloreactive immune response but leave the antigen-specific suppressive arm intact.
- alloreactions in the regulatory milieu of natural suppressor (NS) cells generate large numbers of antigen-specific suppressor cells that in turn maintain tolerance in vivo.
- the natural suppressor cells may play an important role in preventing the development of host versus graft and graft versus host diseases in allogenic bone marrow chimeras, and in immune tolerances in the neonatal and total lymphoid irradiated (TLI) mice.
- Histamine activates human T s cells and enhances the suppressive ability of murine NS cells in vitro. See, Khan et al., J. Immunol. (1985) 134:4.100 and Sansoni et al., J. Clin. Invest. (1985) 75:650. After pretreatment of both human T s cells
- the present invention provides methods for inhibiting at least a portion of an antigen specific antibody response and/or a portion of a T cell proliferative response by the immune system of a mammal comprising administering to the mammal an effective amount of a composition comprising at least one histamine derivative having binding specificity for at least one histamine receptor and optionally administering a predetermined antigen or immunogenic portion thereof.
- the invention also provides methods of treating sensitivity to a particular antigen and methods of treating T cell mediated diseases in a person by administering to the person a therapeutically effective amount of a composition comprising at least one histamine derivative having binding specificity for at least one histamine receptor, e.g. H ⁇ H2, H3, or H x and a pharmaceutically acceptable carrier or diluent.
- a composition comprising at least one histamine derivative having binding specificity for at least one histamine receptor, e.g. H ⁇ H2, H3, or H x and a pharmaceutically acceptable carrier or diluent.
- the histamine derivative is administered simultaneously or sequentially with a predetermined antigen or an immunogenic portion thereof to which the person is sensitive in order to specifically inhibit the antigen specific antibody response and/or the T cell proliferative response to said predetermined antigen or immunogenic portion thereof.
- the histamine derivative is administered to the person simultaneously or sequentially with a peptide having T cell stimulating activity derived from a predetermined antigen such as a protein allergen or autoantigen to which the person may be sensitive and optionally, administered simultaneously or sequentially with the predetermined antigen or immunogenic portion thereof.

- the histamine derivatives may be purified by conventional purification techniques, such as crystallization, or by chromatographic techniques, such as column chromatography, high performance liquid chromatography. preparative thin-layer chromotography, or the like. It is understood that the subject invention includes methods of using derivatives of histamine wherein histamine is connected by a linking group to an amino acid of poly(amino acid) molecule thereby defining a conjugate.
- the histamine derivative may be linked to a carrier such as polypeptides, proteins, glycoproteins or derivatives thereof (all included within the name poly(amino acid).
- the conjugates may serve a variety of functions, changing the physiological . character of the histamine derivative, acting as immunogens, providing for cell specific binding and the like.
- the nature of the histamine derivative may be modified to lesser or greater degrees by adding additional functionalities, substituting groups or the like.
- a group may be substituted for another group, e.g., methyl or trifluoromethyl with carboxyl.
- substitution at histamine or intermediate the ends of the histamine derivative may be desirable.
- the conjugates may be bonded through a wide variety of functionalities to form amide, methyleneamine, thioether, disulfide, sulfonamide, azo, amidine, etc.
- the particular functionality chosen will depend upon the purpose of the conjugate, ease of synthesis, stability of the linking functionality, affect of the linking group on the physical, chemical like.
- the number of histamine derivatives per carrier may be one, or any number greater than one.
- the number of histamine derivatives per carrier molecule is dependent upon the number of appropriate functional groups in the carrier and the stoichiometry used during the coupling reaction.
- Synthesis routes are well known in the art
- One method would involve the preparation of appropriate histamine derivatives where the extended amine side chain or other location on histamine has a suitable functional group.
- One or more functionalized histamine derivatives are then, in turn, coupled to appropriate side chains of the carrier.
- a method of synthesis may involve the initial modification of the carrier by coupling the derivative group moiety containing a further functional group reactive with histamine directly to the carrier side chain.

- Compound 3 has been shown to have H2 receptor activity but not H ⁇ receptor activity, and further has some H x activity.
- a compound which has receptor activity can bind to a specific receptor. It is believed that compounds having Hj receptor activity enhance the suppressive capacity of the natural suppressor cells via H ⁇ receptor mediated mechanisms. It is believed that compounds having H2 receptor activity stimulate intracellular accumulations of cAMP.
- H x receptors are believed to be found only on human monocytes. neutrophils, and HL-60 cells that have been transformed.
- the H x receptor system is believed to play a role in mediating certain immune responses such as suppressing IL-4 secretion from T helper cells, inhibiting natural T-killer cell activity, enhancing suppression caused by natural suppressor cells and increasing the calcium flux in HL-60 cells and human peripheral blood lymphocytes (PBL). Therefore, compounds having H x receptor activity are believed to have an effect on these processes.

Suitable pharmaceutically effective daily total dosages range from about 1 mg/kg to 100 mg/kg.
- the present invention also provides methods using the histamine derivatives of the Formula 1 for inhibiting at least a portion of an antigen specific antibody response to a predetermined antigen, such as a protein allergen or autoantigen, by the immune system of a mammal sensitive to the predetermined antigen (i.e.. the mammal has been producing antibodies to the predetermined antigen).
- a predetermined antigen such as a protein allergen or autoantigen
- an effective amount of a composition comprising at least one histamine derivative of Formula 1 is administered to a mammal sensitive to the predetermined antigen or immunogenic portion thereof (i.e., a portion of an antigen capable of eliciting an immune response) in order to at least partially inhibit further production of antibodies to the predetermined antigen by the immune system of the mammal.
- the predetermined antigen or an immunogenic portion thereof is administered to a mammal sensitive to the predetermined antigen or immunogenic portion thereof, in conjunction with at least one histamine derivative of Formula 1 to specifically inhibit the antigen specific antibody response to the predetermined antigen or immunogenic portion thereof (i.e., further production of antibodies specifically reactive to the predetermined antigen or immunogenic portion thereof is at least partially inhibited).

- a peptide having T cell stimulating activity and derived from a protein allergen or other antigen is administered to a person sensitive to the protein allergen or autoantigen from which the peptide is derived simultaneously or sequentially with a histamine derivative of Formula 1 of the present invention.
- T cell stimulating activity is defined herein as induction of T cell proliferation, lymphokine secretion and/or T cell anergy/tolerization.
- T cell stimulating activity can be tested by culturing T cells obtained from a person sensitive to a protein allergen or other antigen with a peptide derived from the protein allergen or other antigen and determining the presence of proliferation by the T cells in response to the peptide.
- Peptides useful in methods of treating sensitivity to a protein allergen or other antigen have T cell stimulating activity and preferably have human T cell stimulating activity and accordingly comprise at least one T cell epitope of a protein allergen or other protein antigen.
- Peptides derived from protein allergens preferably do not bind immunoglobulin E (IgE) or bind IgE to a substantially lesser extent than the protein allergen from which the peptide is derived binds IgE.
- T cell epitopes are believed to be involved in initiation and perpetuation of the immune response to a protein allergen or other protein antigen which is responsible respectively for the clinical symptoms of allergy or other diseases. These T cell epitopes are thought to trigger early events at the level of the T helper cell by binding to an appropriate HLA molecule on the surface of an antigen presenting cell and stimulating the relevant T cell subpopulation. These events lead to T cell proliferation, lymphokine secretion, local inflammatory reactions, recruitment of additional immune cells to the site, and activation of the B cell cascade leading to production of antibodies.
- T cell epitope is the basic element or smallest unit of recognition by a T cell receptor, where the epitope comprises amino acids essential to receptor recognition and may be contiguous and/or non-contiguous in the amino acid sequence of the protein. Amino acid sequences which mimic those of the T cell epitopes and which modify the allergic response to protein allergens are within the scope of this invention.
- Administration of these peptides may tolerize or anergize appropriate T cell subpopulations such that they become unresponsive to the protein allergen or other antigen and do not participate in stimulating an immune response upon such exposure.
- administration of a peptide comprising at least one T cell epitope of a protein allergen may modify the lymphokine secretion profile as compared with exposure to the naturally-occurring protein allergen or portion thereof.
- exposure to the peptide may influence T cell subpopulations which normally participate in the response to the allergen such that these T cells are drawn away from the site(s) of normal exposure to the allergen (e.g.. nasal mucosa. skin, and lung) towards the site(s) of therapeutic administration of the peptide.
- T cell subpopulations may ameliorate or reduce the ability of a person's immune system to stimulate the usual immune response at the site of normal exposure to the allergen, resulting in a diminution in allergic symptoms.
- the purpose behind administering these peptides is to have the effects caused by the administration of these peptides outlast the immunomodulating effects caused by administration of the histamine derivative.
- peptides When peptides are derived from protein allergens, they can comprise at least one T cell epitope of a protein allergen such as a protein allergen selected from the group consisting of; a protein allergen of the genus Dermatophagoides: a protein allergen of the genus Felis: a protein allergen of the genus Ambrosia: a protein allergen of the genus Lolium: a protein allergen of the genus Cryptomeria; a protein allergen of the genus Alternaria: a protein allergen of the genus Alder: a protein allergen of the genus Betula: a protein allergen of the genus Quercus: a protein allergen of the genus Olea: a protein allergen of the genus Artemisia: a protein allergen of the genus Plantago: a protein allergen of the genus Parietaria: a protein allergen of the genus Canine: a protein aller
- Peptides useful in methods of the invention can be derived from protein antigens other than protein allergens where enhancement or depression of an antigen specific immune response is desired.
- peptides having human T cell stimulating activity of a known autoantigen involved in the pathogenesis of an autoimmune disease or peptides comprising at least one T cell epitope of a known autoantigen can be administered to decrease the antibody response to the autoantigen. to interfere with efficacy and/or decrease immune complex related side effects.
- peptides derived from the autoantigen having human T cell stimulating activity could be defined by standard T cell biology techniques, or if desired, precise T cell epitopes can be defined by fine mapping techniques and a peptide comprising at least one T cell epitope produced.

- SpW-Mb sperm whale myoglobin
- mice Two groups of DBA/2 mice were tested. One group of four mice was a control. The other group of four mice was treated with Compound 3. Both groups of mice were immunized using approximately 100 ⁇ g per mouse of SpW-Mb plus CFA intravenously on day 0. On day-1 and day+2 one group of mice was given approximately 32 mg/kg Compound 3 in buffer i.v.
- mice were killed and the draining lymph nodes were removed and a single cell suspension was made.
- the cells were then plated out in a 96 well U- bottom plate at a concentration of 4 x lO ⁇ cell/ml in media containing 1% mouse serum.
- the cells were then challenged in vitro with antigen diluted at 1. 5. and 25 ⁇ m in media without serum.
- the plates were then placed in the incubator at 37 C .
- the wells were pulsed with tritiated thymidine and on day 5 the plates were harvested. The results are shown in Fig. 2.
- Fel d I protein was purified from an extract of house dust as described by Chapman et al. Briefly, house dust (from vacuum containers used in homes with multiple cats) was extracted with PBS, then lyophilized and redissolved in water. The extract was applied to a column coupled with anti-Fel d I monoclonal antibody (hybridomas 6F9 and 1G4 were both provided by M. Chapman). The Fel d I was 5 eluted from the column with 100 mM glycine pH 2.5 and was neutralized.
- Fel d I was coated onto Immulon 2 (Dynatech, Chantilly, VA) 96-well plates by incubation of 50 ⁇ l/well of 2 ⁇ g/ml Fel d I in PBS overnight at 0 4°C. The wells were incubated with 0.5% gelatin in PBS at 37°C for one hour. Plates were washed three times with PBS-T (1 X PBS + 0.05% Tween 20). Sera were diluted in PBS-T. After incubation at room temperature for one hour and washing with PBS-T, the bound mouse antibody was detected by incubation with biotinylated goat anti-mouse IgG (Southern Biotechnology Associates, Birmingham, 5 AL).
- H-Mb ELISA is carried out similarly, using isotype specific polyclonal reagents.
- Antigen bound IgE was detected similarly, but using biotinylated EM95-1. a rat monoclonal antibody specific for mouse IgE. Biotinylated goat anti-rat IgG (Dirkegaard and Perry) was used as an added signal amplification step in the IgE 5 ELISA.
- Antigen bound IgM was detected similarly, but using anti-mouse IgM. Culture Conditions for Proliferation Assays
- the inguinal, paraaortic. and popliteal lymph nodes were removed from the animals seven days after antigen challenge.
- the cells from these organs were suspended by being forced through a stainless steel mesh with a glass pestal.
- the cells were washed two times in RPMI 1640 with 1% FCS before being cultured. All cells were cultured at 37°C in 57c CO2 in RPMI-1640 with 10% FCS (#F4884.
- helper T cell subsets to augment different antibody isotypes.
- Murine TH ⁇ cells appear to stimulate the production of IgG while TH2 cells stimulate the production of IgGl and IgE.
- histamine congeners can specifically effect different populations of helper T cell functions.
- Two different histamine congeners (Compound 1 and Compound 3 discussed earlier) have been compared for their ability to effect the antibody response to Horse myoglobin (H-Mb).
- H-Mb Horse myoglobin
- the IgM response specific for H-Mb was assayed on day 7 following an antigen priming with a day 0 and day 2 drug treatment (Fig. 9). There was no detectable effect of 35 mg/Kg histamine congener on the antigen specific IgM made in response to the H-Mb priming.
- mice were treated with 35 mg/Kg histamine congener on day (-1) and day 2. These mice received H-Mb on day 0 and day 21. Sera (day 33) from these mice were assayed for H-Mb specific IgG.
- Fig. 3 demonstrates the ability of Compound 1 and Compound 3 to inhibit the production of H-Mb specific IgG.
- Compound 3 appears to decrease the H-Mb specific IgG2a and IgG2b. This implies that the target of Compound 3 activity may be part of the TH * [ pathway. In contrast.
- Compound 1 does not effect the H-Mb specific IgG2a or IgG2b.
- the decrease in IgG found after Compound 1 treatment may reflect an effect on IgGl.
- the ability of Compound 1 to decrease IgG and IgE responses to Fel d I suggests that its target may be the TH2 pathway.
- Receptors for the Histamine congeners are present on most* cells involved in the immune response.
- Experiments have been conducted to define the target of action of coumpound 1 and Compound 3. Mice were primed with Mb and treated _ with drug on day (-2) and (-1 ) (iv). Draining lymph nodes were harvested and antigen specific proliferation was measured (Fig. 6). Antigen specific T cell proliferation is decreased by treatment of the mice with Compound 3. The data implies that the stimulation of specific T cell activation is affected by Compound 3.
- THj activity is responsible for the majority of T cell proliferation in vitro.
- IDDM Autoimmune Disease Model Insulin-dependent diabetes mellitus
- IDDM Autoimmune Disease Model Insulin-dependent diabetes mellitus
- T lymphocytes have been implicated in the destruction of the pancreatic cells and autoantibody production is associated with the development of insulitis, the inflammatory lesion of IDDM.
- a strain of mouse non obese diabetic mice referred to as NOD mice
- NOD mice develops a type of pancreatic lesion that closely resembles Type I diabetes in man.
- Many experiments using immunosuppressive drugs that showed efficacy in NOD mice predicted the value of immunosuppressives in people susceptible to type I diabetes.
- the imunosuppressives available for the treatment of Type I disease in susceptible patients are efficacious but only during the time they are given. Those agents, with the possible exception of anti-CD4 monoclonal antibody, are too toxic to give continuously for prolonged periods.
- the experiments described herein focus on the effects of compounds 1 and 3 on the progress of hyperglycemia and the development of insulitis.
- the experiments focus on the following issues: 1. Whether short courses (two doses) of either drug or the drugs combined alter the onset of hyperglycemia and occurrence of death; 2. Whether protracted dosing of drug at weekly intervals alter the onset of IDDM in any more definitive way than short courses; and 3. Whether intermittent dosing of the two drugs retard or modify the onset or severity of the inflammatory lesion of the pancreas. It is believed that the immunosuppressive effects of the autacoid
- Compound 3 could influence the course of the disease because Compound 3 is capable of inhibiting T Cell proliferation to antigen. It should thus be able to limit a T cell-mediated cytolytic event.
- Fig. 8 shows the absence of any disease in the group treated with compounds 1 plus 3 up to day 140.
- the Examples show that histamine congeners are potent immunosuppressants and each has a different potential mechanism of immunomodulation.
- Compound 1 suppresses T cell dependent IgE, IgGl (but not
- IgM, IgG2a or IgG2b antibody responses In various antigenic responses.
- Compound 3 supresses IgGl, IgG2a and IgG2b but not IgM responses. The effects of Compound 3 on IgE will be tested. Only Compound 3 appears to directly suppress T cell proliferation to specific antigen at the doses tested. The suppression of antibody production is transferable and also can be seen after the response to the antigen is established.
- H ⁇ and H2 receptor effects may be needed and cooperative in the effects on the NOD mouse or the apparent cooperation may simply be additive H2 effects contributed separately by the two drugs; dose dependence and blocking effects of H. ⁇ or H2 blockers will be studied to determine the pharmacologic mechanism by which the experiments work: the cellular mechanism by which the autacoids work are not established by the selectivity of the effects on isotypes and actions of T cell proliferation suggest the target for Compound 3 could be a THj cell.
