Cross-linking of high-affinity immunoglobulin E (IgE) results in the life-threatening allergic reaction anaphylaxis. Yet cellular mechanisms that induce B cells to produce IgE response allergens remain poorly understood. T follicular helper (TFH) direct affinity and isotype antibodies produced by cells. Although TFH cell-derived interleukin-4 (IL-4) is necessary for production, it not sufficient. We report a rare population IL-13-producing present mice humans with allergens, but when...
Loss of RNA homeostasis underlies numerous neurodegenerative and neuroinflammatory diseases. However, the molecular mechanisms that trigger neuroinflammation are poorly understood. Viral double-stranded (dsRNA) triggers innate immune responses when sensed by host pattern recognition receptors (PRRs) present in all cell types. Here, we report human neurons intrinsically carry exceptionally high levels immunostimulatory dsRNAs identify long 3'UTRs as giving rise to neuronal dsRNA structures....
Generation of peanut-specific gut immunoglobulin A antibodies is independent T follicular helper cells.
Summary Ku70 and Ku80 form Ku, a ring-shaped protein that initiates the non-homologous end-joining (NHEJ) DNA repair pathway. 1 Specifically, Ku binds to double-stranded (dsDNA) ends recruits other NHEJ factors ( e.g. , DNA-PKcs LIG4). While RNA (dsRNA) 2 traps mutated-DNA-PKcs on ribosomal in vivo, 3,4 physiological significance of Ku-dsRNA interactions otherwise wild-type cells remains elusive. Intriguingly, while dispensable for murine development, 5,6 is essential human cells. 7 Despite...
