Brain cells can harbor and spread HIV virus to the body

Astrocytes harbor HIV and spread the virus to CD4+ T cells that traffic the virus out of the brain and into other organs. HIV moves via this route, even when the virus is suppressed with cART.

Highly Reproducible Sex Differences in Aspects of Human Brain Anatomy

Analysis of over 2,000 brain scans revealed evidence of highly reproducible sex differences in the volume of different regions of the brain. On average, females had greater cortical volume in the medial and lateral prefrontal cortex, orbitofrontal cortex, superior temporal cortex, and lateral parietal cortex. Males had increased volume in the ventral temporal and occipital brain regions. Gene expression data suggest the potential role of sex chromosomes that contribute to the differences.
