THE BASIC PRINCIPLES OF TAUROCHENODEOXYCHOLATE-3-SULFATE

S1P receptor–mediated sensing of elevated S1P levels during the blood and lymph serves for a normal mechanism to cause the egress of hematopoietic cells from tissues in to the circulation (Figure three). S1P1 expression on T and B cells stimulates their exit from lymphoid tissues, with low S1P stages, into blood or lymph, with substantial S1P ran
