THE 2-MINUTE RULE FOR 6''-O-ACETYLSAIKOSAPONIN A

S1P receptor–mediated sensing of elevated S1P degrees during the blood and lymph serves as a normal mechanism to set off the egress of hematopoietic cells from tissues to the circulation (Figure three). S1P1 expression on T and B cells stimulates their exit from lymphoid tissues, with reduced S1P amounts, into blood or lymph, with large S1P level
