A recent MIT study demonstrates that different mutations within the MECP2 gene, which causes Rett syndrome, result in distinct neurological abnormalities and require targeted, mutation-specific treatments rather than a universal therapeutic approach.

This brief highlights a mechanism by which brain-support cells (astrocytes) can be activated to reduce Alzheimer’s-related plaque and preserve cognition in a model system. For mental health professionals, the material offers insight into the cellular processes that underlie neurodegenerative changes and how glial function may influence cognitive resilience, which can inform considerations of patient care, caregiver education, and interdisciplinary collaboration.

Yet another wrinkle on the Central Dogma of Molecular Biology: protein-templated DNA synthesis!

ABSTRACT
Defense-associated reverse transcriptases (DRTs) are widespread bacterial anti-phage systems that use unconventional mechanisms of polynucleotide synthesis. We show that DRT3, which comprises two distinct RTs (Drt3a and Drt3b) and a noncoding RNA (ncRNA), synthesizes alternating poly(GT/AC) double-stranded DNA. Cryo–electron microscopy structures at 2.6 Å resolution reveal a D3-symmetric 6:6:6 complex of Drt3a, Drt3b, and ncRNA. Drt3a produces the poly(GT) strand using a conserved ACACAC template within the ncRNA. Notably, Drt3b synthesizes a complementary, protein-primed poly(AC) strand in the complete absence of a nucleic acid template, using conserved active site residues specific to Drt3b to enforce precise base alternation. These findings expand the functional landscape of nucleic acid polymerases, revealing a protein-templated mechanism for sequence-specific DNA synthesis.
