1 Studies from this and other laboratories have shown that interleukin-1 alpha (IL-1 alpha) stimulates corticosterone and prostaglandin (PG) release from primary cultures of rat adrenal cells. Corticosterone interleukin 1 alpha Rattus norvegicus
2 Studies from this and other laboratories have shown that interleukin-1 alpha (IL-1 alpha) stimulates corticosterone and prostaglandin (PG) release from primary cultures of rat adrenal cells. Corticosterone interleukin 1 alpha Rattus norvegicus
3 A previous report from our laboratory (1) indicated involvement of the alpha-adrenergic system in IL-1 alpha-stimulated corticosterone secretion from primary cultures of rat adrenal cells. Corticosterone interleukin 1 alpha Rattus norvegicus
4 IL-1 alpha significantly increased (P < 0.05) epinephrine, PGE2, and corticosterone levels above those in medium-treated controls from primary adrenal cells. Corticosterone interleukin 1 alpha Rattus norvegicus
5 In the presence of the alpha-adrenergic antagonist phentolamine (10 microM), IL-1 alpha-stimulated (P < 0.05) corticosterone release was inhibited, whereas IL-1 alpha-induced PGE2 release was not affected. Corticosterone interleukin 1 alpha Rattus norvegicus
6 These observations indicate that IL-1 alpha stimulates corticosterone release through an alpha-adrenergic mechanism that is independent of PGE2 release from primary rat adrenal cells. Corticosterone interleukin 1 alpha Rattus norvegicus
