NK Cells in Mucosal Defense against Infection
Conventional natural killer cells (NK cells) provide continual surveillance for cancer and rapid responses to infection. They develop in the bone marrow, emerge as either NK precursor cells, immature, or mature cells, and disperse throughout the body. In the periphery NK cells provide critical defense against pathogens and cancer and are noted to develop features of adaptive immune responses. I...
متن کاملNK cells play a critical protective role in host defense against acute extracellular Staphylococcus aureus bacterial infection in the lung.
Staphylococcus aureus remains a common cause of nosocomial bacterial infections and are often antibiotic resistant. The role of NK cells and IL-15 and their relationship in host defense against extracellular bacterial pathogens including S. aureus remain unclear. We have undertaken several approaches to address this issue using wild type (WT), IL-15 gene knock-out (KO), and NK cell-depleted mou...
متن کاملNKG2D is critical for NK cell activation in host defense against Pseudomonas aeruginosa respiratory infection.
Pseudomonas aeruginosa is a major cause of nosocomial respiratory infections. The eradication of P. aeruginosa from the lung involves the orchestrated actions of the pulmonary epithelium and both resident and recruited immune cells. The NKG2D receptor is constitutively expressed on the surface of circulating and tissue-resident NK cells (and other cytotoxic lymphocytes), and is capable of contr...
متن کاملCell-Mediated Defense against Infection
e principal function of the mammalian immune system is to combat infectious diseases. Immune responses to antigens and microbial pathogens are divided into those mediated by cells (i.e., cell-mediated immunity) and those mediated by antibodies (i.e., humoral immunity). e T lymphocyte, the “central player” in cell-mediated immunity, provides antigen specicity and orchestrates the antimicrobia...
متن کاملNK and NKT cell-independent contribution of interleukin-15 to innate protection against mucosal viral infection.
Interleukin-15 (IL-15) is essential for the development, maturation, and function of NK and NKT cells, which are critical components of the innate immune defense against viral infections. We recently showed that mice lacking IL-15 and/or NK/NKT cells are significantly more susceptible to intravaginal (IVAG) herpes simplex virus type 2 (HSV-2) infection than control mice. For this study, we exam...
