Toll-Like Receptor Initiated Host Defense against Toxoplasma gondii
Toxoplasma gondii is an intracellular pathogen notable for its ability to establish a stable host-parasite relationship amongst a wide range of host species and in a large percentage of the human population. Toll-like receptor signaling through MyD88 is a critical pathway in initiating defense against this opportunistic protozoan and may also be a mediator of pathology during immune dysfunction...
متن کاملToll-like receptors are temporally involved in host defense.
Toll-like receptors (TLRs) are evolutionarily conserved proteins that recognize microbial molecules and initiate host defense. To investigate how TLRs work together to fight infections, we tested the role of TLRs in host defense against the Gram-negative bacterial pathogen, Salmonella. We show that TLR4 is critical for early cytokine production and killing of bacteria by murine macrophages. Int...
متن کاملImportant role for Toll-like receptor 9 in host defense against meningococcal sepsis.
Neisseria meningitidis is a leading cause of meningitis and sepsis. The pathogenesis of meningococcal disease is determined by both bacterial virulence factors and the host inflammatory response. Toll-like receptors (TLRs) are prominent activators of the inflammatory response, and TLR2, -4, and -9 have been reported to be involved in the host response to N. meningitidis. While TLR4 has been sug...
متن کاملImportance of Toll-like receptor 9 in host defense against M1T1 group A Streptococcus infections.
Timely recognition and elimination of invasive group A Streptococcus (GAS) by innate immunity is crucial to control infection. The intracellular pattern recognition receptor Toll-like receptor 9 (TLR9) promotes macrophage hypoxia-inducible factor-1α levels, oxidative burst and nitric oxide production in response to GAS. TLR9 contributes to GAS clearance in vivo in both localized cutaneous and s...
متن کاملComparative toll-like receptor 4-mediated innate host defense to Bordetella infection.
Bordetella pertussis, B. parapertussis, and B. bronchiseptica are closely related species associated with respiratory disease in humans and other mammals. While B. bronchiseptica has a wide host range, B. pertussis and B. parapertussis evolved separately from a B. bronchiseptica-like progenitor to naturally infect only humans. Despite very different doubling times in vitro, all three establish ...
