Our group has recently shown that the M. leprae Hsp65 aggravated the uveitis in mice; in the present study, we evaluated the action of M. leprae  K409A mutant protein and the synthetic peptides Leader pep and K409A pep (covering amino acids residues 352–371 of WT and K409A proteins of M. leprae Hsp65, resp). Here, HSPD1 is linked to uveitis.
