Age-associated shift in rat dendritic cell T-helper polarizing capacity
(Frontiers Media, 2013)
Almost all cellular components of innate and adaptive immunity undergo age-related remodeling. The findings on age-related
changes in human and mouse dendritic cells (DCs) are conflicting, whereas there is no data on the ...
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 ...
Aging affects the responsiveness of rat peritoneal macrophages to GM-CSF and IL-4
(Springer, New York, 2016)
Macrophages undergo significant functional alterations during aging. The aim of the present study was to investigate changes of rat macrophage functions and response to M1/M2 polarization signals with age. Therefore, ...
Aging diminishes the resistance of AO rats to EAE: putative role of enhanced generation of GM-CSF Expressing CD4+T cells in aged rats
(BMC, London, 2015)
Background: Aging influences immune response and susceptibility to EAE in a strain specific manner. The study was designed to examine influence of aging on EAE induction in Albino Oxford (AO) rats. Results: Differently ...
Age and sex determine CD4+T cell stimulatory and polarizing capacity of rat splenic dendritic cells
(Springer, New York, 2020)
The study investigated influence of sex and age on splenic myeloid dendritic cells (DCs) from Dark Agouti rats. Freshly isolated DCs from young males exhibited less mature phenotype and greater endocytic capacity compared ...
Strain-specific differences in age-related changes in rat susceptibility to experimental autoimmune encephalomyelitis and dendritic cell cytokine gene expression
(Društvo genetičara Srbije, Beograd, 2014)
Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis, a prototype of Th1/Th17-mediated organ-specific autoimmune disease. In the rat, susceptibility to development of these diseases is ...
Influence of aging on germinal centre reaction and antibody response to inactivated influenza virus antigens in mice: sex-based differences
(Springer, New York, 2019)
The study examined sex-specificities in age-related changes in BALB/c mice IgG antibody responses to immunisation with trivalent inactivated split-virus influenza bulk. Aging diminished the total serum IgG antibody responses ...
17 beta-Estradiol influences in vitro response of aged rat splenic conventional dendritic cells to TLR4 and TLR7/8 agonists in an agonist specific manner
(Elsevier, Amsterdam, 2015)
This study was undertaken considering that, despite the broad use of the unopposed estrogen replacement therapy in elderly women, data on estrogen influence on the functional capacity of dendritic cells (DCs), and consequently ...
Sexual dimorphism in rat thymic involution: a correlation with thymic oxidative status and inflammation
(Springer, New York, 2019)
The study investigated mechanisms underlying sex differences in thymic involution in Dark Agouti rats. Adverse effects of aging on thymus were more pronounced in males than in females. Thymi from old males exhibited more ...
Sexual dimorphism in the aged rat CD4+T lymphocyte-mediated immune response elicited by inoculation with spinal cord homogenate
(Elsevier Ireland Ltd, Clare, 2015)
Considering the crucial pathogenic role of CD4+ T cells in experimental autoimmune encephalomyelitis (EAE) and the opposite direction of the sexual dimorphism in the severity of the disease in 22-24-and 3-month-old dark ...
