AB  - Monocytes' plasticity has an important role in the development of rheumatoid arthritis (RA), an autoimmune disease exhibiting greater prevalence in women. Contribution of this phenomenon to sex bias in RA severity was investigated in rat collagen-induced arthritis (CIA) model of RA. The greater severity of CIA in females (exhibiting signs of bone resorption) was accompanied by the higher blood level of advanced oxidation protein products and a more pro-oxidant profile. Consistently, in females, the greater density of giant multinuclear cells (monocytes/macrophages and osteoclasts) in inflamed joint tissue was found. This correlated with the higher frequencies of CCR2- and CX3CR1- expressing cells (precursors of inflammatory monocytes/macrophages and osteoclasts) among CD11b+ splenocytes. This in conjunction with the enhanced migratory capacity of CD11b+ monocytic cells in females compared with males could be linked with the higher frequencies of CCR2+CX3CR1-CD43(low)CD11b+ and CCR2-CX3CR1+CD43(hi)CD11b+ cells (corresponding to "classical" and "non-classical" monocytes, respectively) and the greater density of CD68+ cells (monocytes/macrophages and osteoclast precursors/osteoclasts) in blood and inflamed paws from female rats, respectively. Consistently, the higher levels of GM-CSF, TNF-alpha and IL-6, IL-1 beta (driving Th17 cell differentiation), and IL-17 followed by the lower level of IL-10 were measured in inflamed paw cultures from female compared with male rats. To the greater IL-17 production (associated with enhanced monocyte immigration and differentiation into osteoclasts) most likely contributed augmented Th17 cell generation in the lymph nodes draining arthritic joints from female compared with male rats. Overall, the study suggests the sex-specific contribution of monocytic lineage cells to CIA, and possibly RA development.

AB  - 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 prominent: (i) fibro-adipose degeneration which correlated with greater intensity of thymic oxidative stress and enhanced thymic TGF- and IL-6 expression and (ii) decline in thymopoiesis, as suggested by the number of the most mature CD4+CD8-/CD4-CD8+ single positive (SP) TCRhigh thymocytes. The greater accumulation of adipose tissue in old male thymus was linked with greater age-related increase in thymic expression of PPAR and STAT3, a transcription factor regulating the expression of PPAR downstream genes, in male than in female rats. In aged thymi of both sexes the early CD4-CD8- double negative (DN) stage of thymocyte development was affected, so relative accumulation of the least mature CD45RC+CD2- cells followed by decreased frequency of their DN and CD4+CD8+ double positive (DP) TCR- descendants was observed. Additionally, in old males, because of the increased thymic expression of Nur77, a nuclear receptor involved in negative selection, and decreased CD90 (a negative regulator of thymocyte selection threshold) MFI on DP TCRint thymocytes, less efficient positive/more efficient negative selection was found. Moreover, in male rats, thymocyte post-selection differentiation/maturation was skewed towards CD4-CD8+ SP TCRhigh cells compared with age-matched females, reflecting, at least partly, greater IL-15 expression in their thymi. The study indicated mechanisms underlying sex-based differences in age-related thymic changes and consequently necessity of sex-specific approaches in designing strategies to rejuvenate thymus.
