NK Cell-Mediated Regulation of Protective Memory Responses against Intracellular Ehrlichial Pathogens.
Ehrlichiae are gram-negative obligate intracellular bacteria that cause potentially fatal human monocytic ehrlichiosis. We previously showed that natural killer (NK) cells play a critical role in host defense against Ehrlichia during primary infection. However, the contribution of NK cells to the memory response against Ehrlichia remains elusive. Primary infection of C57BL/6 mice with Ehrlichia...
متن کاملTLR-Dependent Human Mucosal Epithelial Cell Responses to Microbial Pathogens
Toll-like receptor (TLR) signaling represents one of the best studied pathways to implement defense mechanisms against invading microbes in human being as well as in animals. TLRs respond to specific microbial ligands and to danger signals produced by the host during infection, and initiate downstream cascades that activate both innate and adaptive immunity. TLRs are expressed by professional i...
متن کاملInhibition of Toll Like Receptor immune responses by microbial pathogens.
Toll Like Receptors (TLRs) are pathogen recognition receptors (PRRs) that respond to specific pathogen associated molecular patterns (PAMPs) during microbial invasion. After TLR stimulation a series of cellular responses initiate an inflammatory response and influence specific adaptive immunity that ultimately destroy the pathogen. But the immune response is not always able to control the infec...
متن کاملNK cells and immune "memory".
Immunological memory is a hallmark of the adaptive immune system. However, the ability to remember and respond more robustly against a second encounter with the same pathogen has been described in organisms lacking T and B cells. Recently, NK cells have been shown to mediate Ag-specific recall responses in several different model systems. Although NK cells do not rearrange the genes encoding th...
متن کاملCytokine activation induces human memory-like NK cells.
Natural killer (NK) cells are lymphocytes that play an important role in the immune response to infection and malignancy. Recent studies in mice have shown that stimulation of NK cells with cytokines or in the context of a viral infection results in memory-like properties. We hypothesized that human NK cells exhibit such memory-like properties with an enhanced recall response after cytokine pre...
