Previous studies showed that mice with pristane-induced arthritis (PIA) and those protected from the disease by preimmunization with mycobacterial 65-kDa heat shock protein (hsp65) possess raised immune responses to hsp65. Additionally, T cells from hsp65-protected mice, but not from pristane-injected or normal mice, produced the Th2-associated cytokines IL-4, IL-5, and IL-10 in response to sti...
Immunization of Lewis rats with heat-killed Mycobacterium tuberculosis H37Ra leads to development of polyarthritis (adjuvant-induced arthritis; AA) that shares several features with human rheumatoid arthritis (RA). Immune response to the 65-kDa mycobacterial heat-shock protein (Bhsp65) is believed to be involved in induction of AA as well as in experimental modulation of this disease. However, ...
INTRODUCTION Tuberculosis is a major public health threat, annually affecting new individuals worldwide, especially those in developing countries. Rapid detection of the agent and effective treatment are two important factors in controlling this disease. METHODOLOGY The present study aimed to evaluate polymerase chain reaction (PCR) as a rapid and direct molecular method for the diagnosis of ...
introduction: fish mycobacteriosis is caused by the non-tuberculous mycobacteria. infected fish are normally the primary source of infection, although non-tuberculous mycobacteria can be found in the environment. the present study was designed to investigate the few recently found suspected cases of mycobacteriosis in iranian ornamental fish tanks. materials and methods: pathological specime...
Three isolates of a slow-growing, non-chromogenic mycobacterium were grown from three sputum samples of a patient from the north-eastern Ceará state in Brazil. Identification at species level could not be obtained with PCR restriction analysis of the hsp65 gene. In order to characterize the isolates we carried out phenotypic and genotypic tests. We sequenced the nearly complete 16S rRNA gene an...
Most of the therapeutic strategies to control multiple sclerosis are directed to immune modulation and inflammation control. As heat shock proteins are able to induce immunoregulatory T cells, we investigated the therapeutic effect of a genetic vaccine containing the mycobacterial hsp65 gene on experimental autoimmune encephalomyelitis (EAE). Although pVAXhsp65 was immunogenic for mice with EAE...
Mycobacterium avium complex (MAC) species cannot be discriminated by the usual methods of biochemical identification of mycobacteria. This study showed that amplification by PCR of DT1 and DT6, two single copy sequences identified in the genome of M. avium serotype 2, the insertion sequence IS1245, found to be consistently present in M. avium strains and the heat-shock protein gene hsp65, follo...
In rheumatoid arthritis an increased proportion of the N-linked oligosaccharides on serum IgG terminate with N-acetylglucosamine (agalactosyl IgG). It has recently been shown that group A streptococcal cell wall peptidoglycan/polysaccharide complex may be used to raise monoclonal antibodies which bind to this glycoform of IgG. Patients with rheumatoid arthritis also have increased levels of ant...
Arteriosclerotic lesions can be induced in normocholesterolaemic rabbits by immunisation with heat-shock protein (hsp) 65, a stress protein expressed in high concentrations in human atherosclerotic lesions. If an immune reaction to hsp65 also plays a part in human atherogenesis, it should be possible to detect anti-hsp65 antibodies in patients with atherosclerotic lesions. To study the possible...
