Immunoblot studies in the differential diagnosis of porcine brucellosis: an immunodominant 62 kDa protein is related to the mycobacterial 65 kDa heat shock protein (HSP-65)

Protects Against Pristane-Induced Arthritis Mycobacterial 65-kDa Heat Shock Protein An Immunodominant Epitope from

An immunodominant epitope from mycobacterial 65-kDa heat shock protein protects against pristane-induced arthritis.

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...

Cytoplasmic and extracellular expression of pharmaceutical-grade mycobacterial 65-kDa heat shock protein in Lactococcus lactis.

Lactic acid bacteria (LAB) are an attractive and safe alternative for the expression of heterologous proteins, as they are nonpathogenic and endotoxin-free organisms. Lactococcus lactis, the LAB model organism, has been extensively employed in the biotechnology field for large-scale production of heterologous proteins, and its use as a "cell factory" has been widely studied. We have been p...

The production of molecular clones of Toxoplasma gondii-derived heat shock protein 70 kDa

Toxoplasmosis is a common and widespread infection in humans and many other species of warm–blooded animals. Toxoplasma gondii-derived heat shock protein 70 (Hsp70) may play an important role in the virulence of Toxoplasma gondii (T. gondii). In the present study, T. gondii Hsp70 was amplified by polymerase chain reaction (PCR) from the DNA of the T. gondiitachyzoite RH strain through the use o...

Dietary restriction abrogates antibody production induced by a DNA vaccine encoding the mycobacterial 65 kDa heat shock protein

BACKGROUND Protein-calorie malnutrition (PCM) is the most common type of malnutrition. PCM leads to immunodeficiency and consequent increased susceptibility to infectious agents. In addition, responses to prophylactic vaccines depend on nutritional status. This study aims to evaluate the ability of undernourished mice to mount an immune response to a genetic vaccine (pVAXhsp65) against tubercul...
