2003 SEP 10 - (NewsRx.com & NewsRx.net) -- Protective cell-mediated immunity to Listeria monocytogenes occurs in the absence of myeloid differentiation factor 88.
According to recent research from the United States, "In addition to their role in triggering innate immune responses, Toll-like receptors are proposed to play a key role in linking the innate and adaptive arms of the immune response. The majority of cellular responses downstream of Toll-like receptors are mediated through the adapter molecule myeloid differentiation factor 88 (MyD88), and mice with a targeted deletion of MyD88 are highly susceptible to bacterial infections, including primary infection with Listeria monocytogenes (LM)."
"In contrast, herein we demonstrate that MyD88-deficient mice have only a modest impairment in their LM-specific CD4 T cell response, and no impairment in their CD8 T cell response following infection with ActA-deficient LM," reported Sing Sing Way and colleagues at the University of Washington in Seattle. "Furthermore, CD8 T cells from immunized MyD88-deficient mice protected naive recipient mice following ...
