Résumé
Toll-like receptors (TLRs) make a crucial contribution to the innate immune response. TLR5 was expressed in embryoid body derived from mouse embryonic stem cells (mESCs) and βIII-tubulin-positive cells under all-trans retinoic acid-treated condition. TLR5 was upregulated during neural differentiation from mESCs and augmented the neural differentiation of mESCs via nuclear factor-κB and interleukin 6/CREB pathways. Besides, TLR5 was expressed in SOX2- or doublecortin-positive cells in the subgranular zone of the hippocampal dentate gyrus where adult neurogenesis occurs. TLR5 inhibited the proliferation of adult hippocampal neural stem cells (NSCs) by regulating the cell cycle and facilitated the neural differentiation from the adult hippocampal NSCs via JNK pathway. Also, TLR5 deficiency impaired fear memory performance in mice. Our data suggest that TLR5 is a crucial modulator of neurogenesis from mESCs and adult hippocampal NSCs in mice and represents a new therapeutic target in neurological disorders related to cognitive function.
