Definitions
- the present invention relates to the use of natural antibodies of class IgG capable of inducing a high production of IL-1Ra by monocytes or macrophages and to the use of said antibodies for the treatment of inflammatory or autoimmune diseases.
- LTL-1 is a cytokine corresponding to two proteins (IL-la and IL-lb) which play a key role in the inflammatory response (Dinarello CA, Blood, 1996, 87: 2095, 2137).
- 1TL-1 is considered to be the product of activated macrophages, it is also synthesized by lymphoid and non-lymphoid cells such as vascular, epithelial, skin, nerve, dendritic, fibroblastic and chondrocytic cells. It is considered to be a central mediator of the host response to infection and other forms of trauma.
- LTL-1 is a multi-functional cytokine which acts on a wide variety of cells of the immune system as well as other cellular systems. LTL-1 acts directly on the central nervous system, induces the inhibition of insulin secretion by islet cells of the pancreas and stimulates cellular, humoral and natural immune responses.
- LTL-l ⁇ and IL-l ⁇ act by binding to surface receptors expressed on many cells and trigger a series of signals having effects on cell proliferation, apoptosis, induction of cytokines, production of prostaglandins, activation of receptors and secretion of degrading enzymes.
- IL-1a and IL-1b There are two receptors that interact with IL-1a and IL-1b: the type I receptor (80Kd) expressed on T cells, fibroblasts and epithelial cells, which requires interaction with ILIRacP (IL-1 accessory protein) to transmit the signal and the type II receptor (67Kd) expressed on B cells, neutrophils and macrophages which cannot transmit the signal because it is missing the intracellular part.
- lTL-IRa IL-1 receptor antagonist
- These three proteins have 25 to 30% of amino acids in common. LTL-IRa does not associate well with the type II receptor.
- LTL-1 is considered to mediate the defense of the host against infections but also many pathologies and a high level of circulating IL-1 correlates with a variety of clinical situations and in particular septic shock. Its activity is finely regulated at the level of transcription, translation and secretion. Other regulatory mechanisms involve the action of other cytokines, the difference in expression of IL-1 receptors and the production of a natural inhibitor such as IL-1Ra.
- LTL-IRa can act as a competitor of IL-1 and therefore represents an interesting therapeutic agent.
- WO 95/16706, WO 99/36541, WO 01/42305, WO 01/41792 and WO 01/42304 describe the peptide IL-IRa, mutated peptides and their use for the treatment of various pathologies.
- any strategy aimed at specifically stimulating the production of IL-1Ra and therefore at inhibiting the inflammatory activity of IL-1 is of therapeutic interest in the treatment of a certain number of acute or chronic inflammatory pathologies such as rheumatoid arthritis, GVH and others.
- the present invention relates to the use of antibodies capable of strongly stimulating the in vitro (and in vivo) production of lTL-IRa (Interleukin 1 receptor antagonist), but not that of a pro-inflammatory cytokine IL-lb (Interleukin lb and la).
- IgG type human antibodies have the characteristic of recognizing self proteins such as actin, myosin, tubulin, DNA or basic myelin protein (MBP) in ELISA but not vaccine antigens such as tetanus toxoid. They are also selected for their ability to bind to the dinitrophenyl or DNP hapten.
- the invention relates to natural antibodies of class IgG reacting with hapten DNP and at least one autoantigen selected from myosin, actin, basic myelin protein (MBP) and tubulin, characterized in that it induces an overexpression of lTL-IRa at the level of the mRNA and of the secreted protein.
- overexpression means that the level of expression of lTL-IRa is at least 50% higher than the level of expression of cells not stimulated by the antibodies of the invention.
- natural antibodies of class IgG is intended to denote antibodies, fractions or subpopulations of antibodies or monoclonal antibodies exhibiting reactivity with respect to antigens of the self.
- the dTgG subpopulations are prepared from polyvalent dTg or any other intermediate fraction obtained during the process of manufacturing IgINs for therapeutic use.
- such natural antibodies do not react with tetanus toxoid and other non-self antigens.
- these antibodies exhibit a vis-à-reactivity of the hapten DNP greater than 100, 125 or 150 relative to Igin, particularly in relation to TEGELI ⁇ E ®.
- these antibodies have a reactivity rate with respect to at least one autoantigen selected from AD ⁇ , myosin, MBP, actin and tubulin greater than 50, 75 or 100 relative to IgIN versatile, especially compared to TEGELI ⁇ E ® .
- the enrichment rate can be calculated in relation to the activity of the initial polyvalent Ig as a control value in the case of IgG subpopulations or in relation to a reference monoclonal antibody in the case where the natural antibody is a monoclonal antibody.
- the invention in a second aspect, relates to a process for the preparation of an IgG subpopulation defined above, characterized in that it comprises the following steps: a) preparation of an insoluble support on which D ⁇ P is grafted -lysine, b) adsorption of polyvalent Ig on the support obtained in step a), c) elution of the Ig retained on the support so as to collect the fraction interacting with D ⁇ P, d) selection of the fractions exhibiting vis reactivity -to given autoantigens, and e) selection of the fractions inducing overexpression of lTL-IRa by macrophages or monocytes.
- polyvalent Ig can be prepared using other methods.
- TEGELINE ® LLB, France
- retinochoroiditis of the "Birdshot” type pathologies for which Marketing Authorizations have been obtained.
- polyvalent Ig is understood to mean, in the context of the invention, whole polyvalent IgGs, fragments of polyvalent IgGs such as F (ab ′) 2 or F (ab) and any intermediate fractions obtained during the manufacturing process polyvalent IgINs.
- Step a) can be implemented by grafting D ⁇ P-lysine on a solid support, particularly on a Sepharose ® gel, Trisacryl ®, ® of Affiprep 'Affigel ®, or gels activated with C ⁇ Br, or ⁇ HS C 5 H 8 O 2 (glutaraldehyde).
- the IgGs deposited on the solid support obtained in step a) are adsorbed either in the form of polyvalent IgGs dissolved after lyophilization or of polyvalent IgGs in liquid form, or in the form of intermediate fractions obtained during a process for the manufacture of polyvalent IgG in phosphate buffer comprising ⁇ aCl, the concentration of which can vary from 0 M to 3 M.
- the elution of the IgGs retained in step b) is carried out with an ion buffer dissociating the bond between the IgGs and the D ⁇ P, selected in particular from chaotropes such as glycine-HCl or sodium iodide ( ⁇ al) , under conditions varying the pH and / or the molarity of the buffer.
- an ion buffer dissociating the bond between the IgGs and the D ⁇ P selected in particular from chaotropes such as glycine-HCl or sodium iodide ( ⁇ al) , under conditions varying the pH and / or the molarity of the buffer.
- Step d) comprises an ELIS A test carried out on a panel of autoantigens selected in particular from AD ⁇ , actin, myosin, MPB and tubulin or any other self-antigen.
- This step can also include a measurement of the reactivity for a vaccine antigen, for example tetanus toxoid, taking the enrichment rate relative to the activity of the initial polyvalent Ig as a control value.
- Sub-populations with the properties mentioned above are then selected in step e), ie sub-populations inducing the overexpression of mRNA and of IL-IRa protein by macrophages or monocytes . It is considered that there is overexpression when a significant increase in expression is detected compared to the basic expression observed naturally in macrophages or monocytes (for example an increase greater than 50% or more (for example 100% or 200%).
- the invention also relates to the sub-populations capable of being obtained from this process.

- the clones identified in step b) can be fused with a non-Ig secreting myeloma.
- the autoantigen can be selected from DNA, actin, myosin, basic myelin protein (MBP) and tubulin.
- the invention in another aspect, relates to clones of B cells transformed by EBV selected, fused or not with a myeloma and amplified by the method mentioned above. These clones are characterized in that they produce natural monoclonal antibodies capable of inducing overexpression of lTL-IRa by macrophages or monocytes.

- Example 2 Obtaining natural monoclonal human antibodies having the property of stimulating the production of IL1-Ra.
- Example 2.1 Production of monoclonal antibodies from human peripheral blood lymphocytes from an immunized donor.
- a series of human monoclonal antibodies (mAbs) have been obtained after transformation by the EBV virus of B lymphocytes originating from the blood of donors immunized with red Rh + cells. These antibodies are all of the IgG 1 type and have the property of agglutinating the Rh + red blood cells. They are therefore specific for the D antigen.
- Table 3 ELISA reactivity of monoclonal anti-D with respect to TEGELINE ® vis-à-vis more antigens.
- the supernatant of THP1 cells stimulated by Acm D41 and D32 contains large quantities of IL1-Ra whereas at the same concentrations, Acm D35 and D83 induce only a small production of this cytokine (FIG. 7 ).
- Example 2.2 Production of monoclonal antibodies from human peripheral blood lymphocytes from a healthy donor.
- B cells from the blood of healthy donors were transformed with EBV and cultured at the rate of 10 cells per well.
- the supernatants from the wells were tested for the presence of IgG capable of recognizing hapten DNP and actin in ELISA.
- the four most positive wells were pooled (Cl) and cloned by dilution to 1000, 100, 50 and 10 cells per well.
- the same approach was used to select negative wells with anti-DNP and actin (C2) activity (Table 4).
- Table 4 Reactivity in ELISA of purified IgGs originating from culture supernatants of human EBN + B cells with respect to several antigens.
- the cells of wells C1 and C2 were amplified to obtain quantities of antibodies sufficient to be purified on protein G.
- the antibodies obtained are of the IgG type and Table 4 present the results of two purifications carried out using supernatants taken on D +7 (preparation 1) and D + 14 (preparation 2) and show that the purified IgGs of the well Cl recognize the DNP and are reactive for a certain number of autoantigens.
- C2 wells IgG possess no enhanced activity compared to TEGELINE ®.
- the IgGs purified from the two wells C1 and C2 were incubated at a dose of 25 ⁇ g / ml in the presence of THP1 cells. Cell growth is inhibited in the presence of Cl IgG but not of C2 (data not shown) and only Cl IgG stimulates the in vitro production of dTL-IRa by THP1 cells (FIG. 8).
- the cells from wells Cl and C2 are being cloned at 0.5 cells per well to obtain monoclonal IgGs.
