Interested in immune response variability - causes & consequences
Delighted to be in beautiful Tartu sharing our experience studying immune variability in @milieuinterieur.bsky.social with SySAge & University Tartu

this seems apt ..

Lastly, leveraging a recent 10 year follow up study of a subset of the cohort we saw decreases in specific androgens in men who later developed different diseases (but not in women), again raising many interesting questions which are currently being addressed.

Genetic and proteomic analyses also revealed strong associations across the cohort and in sex specific ways

Alternatively smoking had a strong effect on most hormones only in men, raising interesting further questions and illustrating the importance of studying sex specific effects

Studying donors from the existing @milieuinterieur.bsky.social cohort allowed us to study genetic and environment contributions in a healthy context - leading to striking observation that many steroid hormone levels, beyond sex hormones, are influenced by oral contraceptive use in women

Our objective was to expand knowledge and understanding of steroid hormone levels, including corticoids & sex hormones, in healthy women and men over a broad age range. This analysis of a large number of hormones in 1,000 healthy people, fills a major gap in knowledge of these essential molecules

Worries about future of Pubmed, great summary here

We used 10 year follow up data on the same cohort to identify specific hormonal decline in male donors that associate with poor health status. This supports that specific male hormones may decline with poor health, rather than with aging, per se, as generally believed.

Hormonal birth control had a wider impact than anticipated on steroid levels, profoundly repressing estrogens, progestogens, and androgens and significantly increasing glucocorticoids compared to not only post-menopausal women, but also premenopausal women not taking birth control

We found that nearly all steroids exhibited sex or age-related variation between 20-69 years

We also saw that many of cohort were no longer healthy based on our original definition or had developed specific diseases. Applying a biological ageing score between these groups revealed significant differences at both time points - understanding the underlying biology is the focus of ongoing work

We observed expected signs of ageing such as increased BMI and blood pressure, compared physiological measures over 10 years, and studied evolution of antibody responses including exposure to new infections.

Curious how smoking affects immunity? delighted to share our @Nature study we show smoking increases inflammatory response to bacteria & specific T cell responses, inflammatory effect is lost upon smoking cessation but T cell response maintained for years www.nature.com/articles/s41...
