Changes in thymopoiesis in myasthenia gravis
(Taylor & Francis Ltd, Abingdon, 2005)
This study was undertaken to investigate T-cell maturation ill hyperplastic thymi of patients suffering from myasthenia gravis (MG). For this purpose, the expression of the major differentiational molecules (CD4, CD8, and ...
IgE cross-reactivity between meadow fescue pollen and kiwi fruit in patients' sera with sensitivity to both extracts
(Hogefre and Huber Publishers, 2002)
Background: The presence of IgE reactivity to kiwi fruit and grass pollen allergens which could be caused by cross-reactivity has been detected in many patients with allergy. Proper identification of allergens as well ...
Ethanol consumption affecting some brain proteins and cortical plasticity might disturb the neural networks of long-term memory
(IEEE, New York, 2004)
The objective of this study is to investigate whether chronic ethanol consumption include brain damage expressed as; an increase of antibody titer to S-100 and synaptic membrane proteins, additioning of lateral ventricles ...
Beta-endorphin differentially affects inflammation in two inbred rat strains
(Elsevier, Amsterdam, 2006)
It has been shown that inflammation of rat paws elicits accumulation of opioid peptide is-endorphin-containing immune cells in the inflamed subcutaneous tissue, contributing to immumocyte-produced pain suppression. However, ...
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 ...
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 ...
Modulation of humoral immune responses in the rat by centrally applied Met-Enk and opioid receptor antagonists: functional interactions of brain OP1, OP2 and OP3 receptors
(Elsevier, Amsterdam, 2000)
We have previously demonstrated that central application of leucine-enkephalin (Leu-Enk) elicits potentiation and suppression of humoral immune responses through OP1 (delta) and OP2 (kappa) receptors, respectively. ...
Effects of beta-adrenoceptor blockade on the phenotypic characteristics of thymocytes and peripheral blood lymphocytes
(Taylor & Francis Ltd, Abingdon, 2003)
The study revealed that beta-adrenoceptor blockade with propranolol (0.40 mg/100 g/day, s.c.) in adult male DA rats: (i) increased the thymocyte proliferation and apoptosis, (ii) caused disturbances in kinetics of T cell ...
Thymopoiesis following chronic blockade of beta-adrenoceptors
(Taylor & Francis Ltd, Abingdon, 2003)
The present study was undertaken in order to further clarify putative role of the adrenergic innervation in the regulation of the intrathymic T-cell maturation. For this purpose adult male DA rats were subjected to either ...
