WebbB cell receptors assist with antigen binding, as well as internalization and processing of the antigen. B cell receptors also play an important role in signaling pathways. After the antigen is internalized and processed, the B cell can initiate signaling pathways, such as cytokine release, 7 to communicate with other cells of the immune system. WebbIn particular, we have worked on soluble proteins involved in the innate recognition of bacteria such as soluble CD14 and MD-2, as well as in the Toll-like receptors activated by Gram-negative and Gram-positive bacteria. Another area of study is the molecular pathogenesis and cell signaling of ventilator-induced lung injury, and lung ...

WebbLECs orchestrate innate antifungal immunity by augmenting the numbers of interleukin-17A (IL-17A)- and granulocyte-macrophage colony-stimulating factor (GM-CSF)-producing innate lymphocytes, specifically ‘‘natural’’ Th17 (nTh17) cells. Innate lymphocyte-derived IL-17A and GM-CSF in turn enable phagocyte-driven fungal killing. WebbThus, the innate immune system must “get by” using only a limited number of receptors that are active against as wide a variety of pathogens as possible. This strategy is in stark contrast to the approach used by the adaptive immune system, which uses large numbers of different receptors, each highly specific to a particular pathogen.

Webb14 apr. 2024 · Innate immunity is the body’s first line of defense against viral invasion. IAV is first recognized by pattern recognition receptors (PRRs), including retinoic acid-inducible gene I (RIG-I), melanoma differentiation-associated gene 5 (MDA5), and toll-like receptor 3 (TLR3) [7,8,9,10].
