A Comprehensive Atlas of AAV Tropism in the Mouse
Walkey et al., Molecular Therapy. 2025.
https://pubmed.ncbi.nlm.nih.gov/39863928
Over the past three decades, adeno-associated viruses (AAVs) have emerged as the leading viral vector for in vivo gene therapy. This study presents a comprehensive atlas of AAV tropism in male and female mice, evaluating 10 naturally occurring AAV serotypes across 22 tissues using systemic delivery. Researchers employed a fluorescent protein activation approach to visualize AAV transduction patterns and detected transduction of unexpected tissues, including in adrenal glands, testes, and ovaries. Biodistribution closely matched the fluorescent signal intensity. This publicly available data set provides valuable insights into AAV vector targeting and supports optimal serotype selection for basic research and preclinical gene therapy applications in murine models.

Association of Age at Menopause and Hormone Therapy Use With Tau and β-Amyloid Positron Emission Tomography
Coughlan et al., JAMA Neurology. 2023.
https://pubmed.ncbi.nlm.nih.gov/37010830/
To understand the predominance (70%) of women among individuals with Alzheimer’s disease, the investigators studied regional tau and β-amyloid (Aβ) in relation to age at menopause and hormone therapy (HT) in postmenopausal women and age-matched men using positron emission tomography. The study demonstrated that females exhibited higher tau deposition compared with age-matched males, particularly in the setting of elevated Aβ; earlier age at menopause and late initiation of HT were associated with increased tau vulnerability. This study suggests female individuals with these conditions may be at higher risk of pathological burden. Supported by ORIP (S10OD025245), NIA, and NICHD.
