Strain developmentDeveloped by Dr. Kensuke Miyake, The University of Tokyo in 2000.
Strain descriptionC57BL/6-PRAT4A<tm1Kmiy>. Immune cells such as dendric cells (DCs) and macrophages express multiple Toll-like receptors (TLRs) which recognize a variety of pathogen products. A protein associated with TLR4 (PRAT4A) has been found to bind TLR4, and regulate the expression of TLR4 and the response to LPS. Using PRAT4A-deficient mice, there are defective cytokine production against bacteria and activation of Th1 responses. DCs, macrophages and B cells lacking PRAT4A have impaired responses to a variety of TLR ligands. The PRAT4A-deficient bone marrow chimera mice are resistant to lethal-dose LPS administration in the LPS-induced sepsis model to analyze in vivo immune response. This mutant mouse is useful for the study of PRAT4A in innate and adaptive immunity.
