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 ...
Changes in immunological and neuronal conditions markedly altered antibody response to intracerebroventricularly injected ovalbumin in the rat
(Karger, Basel, 1997)
The serum antibody response to ovalbumin (OA) has been investigated following intracerebroventricular (i.c.v.) and intravenous administration of antigen in the rat, under altered neuronal and immunological conditions. ...
Age-Associated Remodeling of Neural and Nonneural Thymic Catecholaminergic Network Affects Thymopoietic Productivity
(Karger, Basel, 2011)
Ageing is associated with a progressive decline in thymic cytoarchitecture followed by a less efficient T cell development and decreased emigration of naive T cells to the periphery. These thymic changes are linked to ...
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 ...
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 ...
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 ...
Propranolol Impairs Primary Immune Responses in Rat Experimental Autoimmune Encephalomyelitis
(Karger, Basel, 2019)
Objective: We examined the effect of beta-adrenoceptor (AR) blockade in the preclinical phase of experimental autoimmune encephalomyelitis (EAE), the most commonly used model of multiple sclerosis, on the development of ...
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 ...
