Age-related effect of peptide YY (PYY) on paw edema in the rat: The function of Y1 receptors on inflammatory cells
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
It is well documented that neuropeptides participate in local inflammatory reaction and modulate functions of inflammatory cells. The aim of the study was to determine a link between in vivo and in vitro effects of NPY-related ...
Strain specificities in age-related changes in mechanisms promoting and controlling rat spinal cord damage in experimental autoimmune encephalomyelitis
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
The study investigated strain specificities in age-related differences in CD8+ T cell-and microglial cell-mediated mechanisms implicated in induction/perpetuation and/or control of neuroinflammation in experimental autoimmune ...
Age-associated plasticity of alpha 1-adrenoceptor-mediated tuning of T-cell development
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Alpha(1)-adrenoceptors (alpha(1)-ARs) are involved in neuro-thymic and thymic intercellular communications, and consequently modulation of T-cell development. Ageing is associated with a number of changes in noradrenergic ...
Sex as a confounding factor in the effects of ageing on rat lymph node t cell compartment
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The study examined the influence of sex on the alterations occurring with ageing in rat lymph node (LN) T cell compartment. In female and male rats the decrease in LN T cell counts was followed by a shift in CD4+/CD8+ T ...
Strain specificities in influence of ageing on germinal centre reaction to inactivated influenza virus antigens in mice: Sex-based differences
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Considering variability in vaccine responsiveness across human populations, in respect to magnitude and quality, and importance of vaccines in the elderly, the influence of recipient genetic background on the kinetics of ...
Age-associated changes in CD90 expression on thymocytes and in TCR-dependent stages of thymocyte maturation in male rats
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
To elucidate the effects of ageing on T-cell-maturation, in 3- and 18-month-old rats, we analysed the expression of: (i) CD4/CD8/TCR alpha beta and (ii) Thy-1, which is supposed to be a regulator of TCR alpha beta signalling, ...
Age-associated changes in rat immune system: Lessons learned from experimental autoimmune encephalomyelitis
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Aging is associated with the decline in immune response to infectious agents and tumors and increasing risk of autoimmunity, but the incidence of autoimmune diseases does not increase in the elderly. To elucidate the ...
The influence of aging and estradiol to progesterone ratio on rat macrophage phenotypic profile and NO and TNF-alpha production
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The phenotype and function of tissue macrophages substantially depend on the cellular milieu and biological effector molecules, such as steroid hormones, to which they are exposed. Furthermore, in female rats, aging is ...
The involvement of estrogen receptors alpha and beta in the in vitro effects of 17 beta-estradiol on secretory profile of peritoneal macrophages from naturally menopausal female and middle-aged male rats
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
The systemic and extra- gonadal levels of 17 beta-estradiol (E2) change during aging, and affect the expression of estrogen receptors (ERs) in the immune cells of both females and males. The age-related cessation of ovarian ...
Strain-dependent response to stimulation in middle-aged rat macrophages: A quest after a useful indicator of healthy aging
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Rats of Albino Oxford (AO) strain in our animal facility exhibit a longer average healthy life span than rats of Dark Agouit (DA) strain. Since chronic activation of macrophages contributes to chronic low level inflammation ...
