Tumor and Microenvironment Evolution during Immunotherapy with Nivolumab.

abstract：:Activins are involved in the regulation of multiple biological events, ranging from early development to pituitary function. To characterize the cellular mechanisms involved in these processes, cDNAs coding for an activin receptor were cloned from AtT20 mouse corticotropic cells by screening COS cell transfectants for...
