Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...

Mixed Gonadal Dysgenesis: A Comprehensive Review of Clinical Spectrum, Diagnostic Strategies, and Management Approaches

Clinical Endocrinology, Volume 104, Issue 2, Page 92-102, February 2026.
ABSTRACT Background Mixed gonadal dysgenesis (MGD) is a rare form of differences in sex development (DSD) typically associated with 45,X/46,XY mosaicism. The phenotypic presentation of MGD varies from atypical genitalia to typical male or female appearances often associated with Turner stigmata.

Vertebrate endocrine disruptors induce sex-reversal in blue mussels

Scientific Reports
Mollusks are the second most diverse animal phylum, yet little is known about their endocrinology or how they respond to endocrine disrupting compound (EDC) pollution. Characteristic effects of endocrine disruption are reproductive impairment, skewed sex

A Systematic Review Investigating the Psychosocial Factors Influencing Initiation, Use and Subjective Experience of Performance and Image‐Enhancing Drugs in Women Who Weight‐Train

Drug and Alcohol Review, Volume 45, Issue 2, February 2026.
ABSTRACT Issue Performance and image‐enhancing drug (PIED) use among women is a growing phenomenon, particularly within weight‐training populations. Despite increasing prevalence, research on the psychosocial factors involved in women's PIED use remains emergent and fragmented.

Longitudinal sex differences in cerebrovascular ageing in older adults: results from the brain in motion study

The Journal of Physiology, Volume 604, Issue 3, Page 1088-1112, 1 February 2026.
Abstract figure legend Longitudinal assessment of sex differences in cerebrovascular ageing over a ∼6 year period: the Brain in Motion study. Cerebrovascular function was assessed at baseline (T1) and at a follow‐up (T2) ∼6 years later, at rest, during euoxic hypercapnia and while engaging in submaximal exercise. Over the follow‐up period females had a

Steroid hormone-deprived sex reversal in cyp11a1 mutant XX tilapia experiences an ovary-like stage at molecular level

Communications Biology
Fish sex is largely influenced by steroid hormones, especially sex hormones. Here, we established a steroid hormone-free genetic model by mutation of cyp11a1 in Nile tilapia, which was confirmed by EIA assay.
