Investigating how gender-affirming hormone therapy affects immune function

Understanding the effects of Gender Affirming Hormone Therapy (GAHT) on immune function using a systems immunology approach

['FUNDING_R21'] · MURDOCH CHILDREN'S RESEARCH INSTITUTE · NIH-10912044

This study is looking at how hormone therapy affects the immune system in transgender people, specifically by checking blood samples from transgender women before and after they start treatment to see how the hormones might change their immune responses and risk of infections.

What this research studies

This research explores the impact of gender-affirming hormone therapy (GAHT) on the immune system of transgender individuals. By analyzing blood samples from transgender women before and after starting GAHT, the study aims to understand how feminizing (estradiol) and masculinizing (testosterone) hormones influence immune responses and susceptibility to infections. The research employs advanced systems immunology techniques to assess changes in immune profiles and plasma metabolites, which are crucial for understanding health outcomes in this population.

Who could benefit from this research

Good fit: Ideal candidates for this research are transgender women who are currently on or considering gender-affirming hormone therapy.

Not a fit: Patients who are not transgender or those who are not undergoing hormone therapy may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved health management and tailored treatments for transgender individuals undergoing hormone therapy.

How similar studies have performed: Previous research has shown promising results in understanding the effects of hormone therapy on various health aspects, but this specific approach to immune function is relatively novel.
