A Toll-Like Receptor-2-Directed Fusion Protein Vaccine against Tuberculosis

A Toll-like receptor-2-directed fusion protein vaccine against tuberculosis.

A fusion protein designated CSU-F36 was constructed that consisted of acylated Rv1411, a potent Toll-like receptor-2 agonist, fused to ESAT-6, a well-characterized immunogenic protein from Mycobacterium tuberculosis. The CSU-F36 fusion protein strongly induced interleukin 12 secretion from macrophages and induced the increased accumulation of CD4 T cells capable of secreting gamma interferon in...

Toll-like receptor 2 ligand-induced protection against bacterial endophthalmitis.

BACKGROUND Activation of innate immunity plays a key role in determining the outcome of an infection. Here, we investigated whether Toll-like receptors (TLRs) are involved in retinal innate response and explored the prophylactic use of TLR2 ligand in preventing bacterial endophthalmitis. METHODS C57BL/6 mice were given intravitreal injections of Pam3Cys, a synthetic ligand of TLR2, or vehicle...

Through Toll-Like Receptor-2 Protein Induces Macrophage Apoptosis Mycobacterium tuberculosis The 19-kDa

Cooperation of Toll-like receptor 2 and 6 for cellular activation by soluble tuberculosis factor and Borrelia burgdorferi outer surface protein A lipoprotein: role of Toll-interacting protein and IL-1 receptor signaling molecules in Toll-like receptor 2 signaling.

Toll-like receptor 2 (TLR2) and TLR4 play important roles in innate immune responses to various microbial agents. We have previously shown that human dermal endothelial cells (HMEC) express TLR4, but very little TLR2, and respond to LPS, but not to Mycobacterium tuberculosis 19-kDa lipoprotein, unless transfected with TLR2. Here we report that HMEC are unresponsive to several additional biologi...

Correlation between Salivary Toll Like Receptor-2 Concentration and Early Childhood Caries

Background: Early childhood caries (ECC) is a common health problem in the developing countries. Basic knowledge about the etiology and pathogenesis of ECC plays an important role in its prevention. Objective: To determine the relationship between salivary TLR-2 concentration and early childhood caries formation Methods: Twenty-Eight children with ages ranging from 36 to 71 months (15 in ECC gr...
