A Cell‐Intrinsic Role for RANK in Regulatory T Cells of the Human Thymus

open access: yesEuropean Journal of Immunology, Volume 56, Issue 2, February 2026.
We identified RANK (TNFRSF11a) expression in human thymic FOXP3+ Tregs, revealing a previously unknown role for the RANK‐RANKL axis in human tTreg development. We show that IL‐2 and IL‐15 can drive RANK expression in CD4+ tTregs, which in turn may modulate their maturation and proliferation within the thymic environment. Created in BioRender. Biorender,

Using artificial intelligence as a technological tool in gynecologic and obstetric health: A narrative literature review

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 172, Issue 2, Page 850-865, February 2026.
Abstract Maternal mortality remains a critical global public health issue, particularly in low‐ and middle‐income settings where failures in surveillance, early diagnosis, and clinical decision making compromise obstetric care. In this context, the present study aimed to critically review the scientific literature on the use of artificial intelligence (
