Peripheral effects of methionine-enkephalin on inflammatory reactions and behavior in the rat
(Karger, Basel, 2000)
Methionine-enkephalin (Met-Enk) induces notable alterations in immune and central nervous system functions. The present study was conducted in order to compare peripheral and central effects of Met-Enk on nonspecific ...
Castration of sexually immature rats affects sympathetic innervation of the adult thymus
(Karger, Basel, 2000)
It has been hypothesized that maturational processes within the hypothalamo-pituitary-gonadal (HPG) axis and thymus are reciprocally regulated via neural pathways. To test this hypothesis, in the thymi of adult rats ...
Methionine-enkephalin stimulates hydrogen peroxide and nitric oxide production in rat peritoneal macrophages: Interaction of mu, delta and kappa opioid receptors
(Karger, Basel, 2004)
Objective: Methionine-enkephalin ( MET) modulates various functions of macrophages related to both immune and inflammatory reactions in a naloxone reversible manner, suggesting that opioid receptors are involved in the ...
Age-Associated Remodeling of Thymopoiesis: Role for Gonadal Hormones and Catecholamines
(Karger, Basel, 2008)
The present review summarizes recent data on age-related thymic changes termed thymic involution, and highlights the putative role of perturbances in extrathymical and, possibly, intrathymical production of gonadal steroids ...
The effects of corticosterone and beta-endorphin on adherence, phagocytosis and hydrogen peroxide production of macrophages isolated from Dark Agouti rats exposed to acute stress
(Karger, Basel, 2008)
Background: Given that stressful experiences can change the reaction to a subsequent exposure to stress, we tested the in vitro effects of the stress mediator corticosterone and the opioid peptide beta-endorphin on the ...
Neonatal androgenization affects the intrathymic T-cell maturation in rats
(Karger, Basel, 2005)
The thymus structure, expression of CD4/CD8/TCR alpha beta on thymocytes and thymocyte proliferative and apoptotic indexes were analyzed in sexually immature 30-day-old and in sexually mature 60-day-old female rats neonatally ...
