Toll like receptors and myeloid cells in development and disease
 Balounová, Jana ; Filipp, Dominik (advisor) ; Špíšek, Radek (referee) ; Vannucci, Luca Ernesto (referee)
Toll like receptors (TLRs) are germline-encoded pattern recognition receptors (PRRs) that play a central role in host cell recognition and responses to pathogens. Primarily they are responsible for induction and regulation of the innate and adaptive immune responses whereby the effector function is executed chiefly by differentiated myeloid cells. Somewhat unexpectedly, TLRs have been also shown to be involved in direct pathogen sensing by bone marrow-derived hematopoietic stem cells (HSCs) and hematopoietic progenitors when, under inflammatory conditions, the rapid generation of innate immune effector cells that effectively combat the infection is of utmost priority. While it has been recognized that the release of inflammatory cytokines from inflamed tissues along with the changes in proportions of differentiating cells in the bone marrow (BM) as well as the BM niche can nudge the differentiation of adult BM-derived cells towards myeloid cells and granulocytes, a direct role of TLRs expressed by HSCs in this process has been demonstrated only recently. However, whether a similar mechanism operates also during embryonic hematopoiesis is unknown. Here we show that TLRs and their adaptor proteins are functionally expressed during early stages of embryogenesis by short-lived maternally-transferred...
