Definitions

  • the present invention relates to polypeptides and fragments thereof, to their use in the prevention, diagnosis and treatment of auto-immune disease such as rheumatoid arthritis, and to methods of preparing these fragments.
  • Autoimmune diseases are thought to arise as a result of similarities between a foreign molecule or antigen and a molecular structure of the organism itself. Chronic forms of arthritis are thought to involve autoimmunity to constituents of the joints in particular of the connective tissues of the body.
  • RA ⁇ Rheumatoid arthritis
  • the disease is the third most common of the elderly and causes a tremendous burden of pain and suffering. It has been known for some time that an association exists between HLA-DR4 and RA suggesting a T-cell involvement [Stasney, New Eng. J. Med. (1978) 298:869 and Watanabe et al, J. exp. Med. (1989) 169:2263] and a genetic contribution to the disease.
  • recent twin studies [Silman ⁇ t al, Brit. J. Rheumatol.
  • pristane-induced arthritis This model is based upon the finding that a proportion of mice injected intraperitoneally with the paraffin oil pristane (2, 6, 10, 14-tetramethylpentadecane) develop a chronic T-cell dependent inflammatory arthritis between 60 and 200 days later depending on the strain of mice [Potter M, J. Immunol. (1981) 127:1591, Bedwell et al, J. Immunol. (1987) 25:393, Wooley et al, Arthritis. Rheum. (1987) 32:1022, Wooley et al. Arthritis. Rheum.
  • Chat heat shock proteins are immunodominant antigens in a number of infectious diseases, such as tuberculosis and leishmania. These infectious diseases can have similar abnormalities as observed in RA such as raised agalactosyl-IgG levels, the organs involved and range of autoantibodies present. Since environmental factors are clearly important in RA, microbial agents and hence hsp's were implicated.
  • Hsps are grouped in gene families according co their molecular weight and sequence homology within individual groups.
  • hsp60 (60KD) gene family includes members hsp65 (mycobacterial) and hsp5 ⁇ (mammalian) .
  • mice become sensitised to hsp by exDOsure to microbial flora in the environment and that this process is necessary for the induction of arthritis by pristane injection. If so, it would be predicted that there is a relationship between sensitisation to hsp65 and susceptibility to PIA. Experiments carried out by the applicants suggest that this hypothesis is correct.
  • hsp 58 has been detected in the joints of patients with RA [Karlsson-Parra et al, Scand. J. Immunol. (1990) 31:283] and T-cells from mice with PIA react with joint extracts [Thompson et al, Eur. J. Immunol. (1990) 20:2479] it seems reasonable to postulate that hsp58 could be a target antigen in the joints of mice developing PIA.
  • mice with PIA and animals protected from the development of arthritis by hps65 preim unisatiOn exhibit elevated immune responses to the 65kD mycobacterial heat shock protein. It would be expected that only mice with PIA should develop autoimmune responses to the 60kD family of hsps whereas the response of mice pre-immunised with hsp65 should be restricted to microbial specific determinants. In other words, the response elicted by immunisation with hps65 in IFA differs from that induced by sensitisation with environmental/bowel microorganisms.
  • T cell-mediated response to mycobacterial antigens has been implicated in the pathogenesis of inflammatory arthritis both in experimental animal models and in man. In adjuvant arthritis in rats, it has been established that the disease can be initiated by T cell clones specific for the 65-kDa mycobacterial heat-shock protein.
  • Rats may also be protected to subsequent adjuvant arthritis induction by pre-immunisation with either a 65 KDa specific T cell line cr with the hsp itself (Van Eden et al., Nature, 1988, 331:171 and Holoshitz et al. , Science 1983, 219:56) .
  • EP-A-322990 describes polypeptides having amino acid sequence 172-192 of a bacterial hsp 64 and their use as immunogens for inducing resistance to auto-immune disease.
  • WO 92/04049 discloses that a peptide comprising the amino acid sequence corresponding to positions 180-186 of the Mycobacterium tuberculosis protein hsp65 is effective in the prevention and treatment of immune-related disease such as autoimmune arthritis.

However, m 302-314 clearly appears to give a significant reduction or nearly 4 fold in the percentage arthritis.
