The present invention extends to a blood control catheter valve for use in a catheter adapter. The blood control catheter value employs an actuator for bypassing a septum to open the blood control catheter valve. The actuator includes flexible retention arms positioned on one end which retract into the body of the actuator while the end of the actuator passes through the septum, and then expand outwardly to maintain the actuator positioned within the septum. This design facilitates the manufacturing of catheter adapters (as well as blood control catheter valves and other components that attach to the catheter adapter) because the design can reduce the tolerance requirements of such components. Further, the design provides a reliable blood control catheter valve that does not require the catheter adapter to be increased in size to accommodate the valve.

The present invention relates to methods for identifying compounds that can reduce immune rejection, for example, transplant- or autoimmune disorder-related immune rejection. The present invention is based, in part, on the discovery, demonstrated herein, that immune rejection can be monitored by determining the amount of particular members of the Jak / Stat signal transduction pathway present within an affected tissue. The present invention is further based, in part, on the discovery, demonstrated herein, that immune rejection can be reduced and tolerance can be induced by modulating the amount of these particular members of the Jak / Stat signal transduction pathway present, expressed or active within an affected tissue. In particular, the results demonstrate that immune rejection can be monitored by determining the amount of mRNA or protein of Stat1, Stat3, Stat4, Stat6, SOCS1, or SOCS3 present, e.g., in an affected tissue.
