Chromaffin Versus Platelet Granules: What We Have Learned From Chromaffin Cells for Human Studies

Journal of Neurochemistry, Volume 170, Issue 5, May 2026.
Chromaffin cells and platelets both utilize exocytosis to release biogenic amines stored within large dense‐core vesicles—specifically chromaffin granules (epinephrine) and δ‐granules (serotonin). While the chromaffin cell is the foundational model for studying the secretory pathway, platelets offer a highly accessible human cell source for clinical ...

Parasitic Infections and Associated Cognitive Outcome Among School‐Aged Children in Africa: A Systematic Review

Brain and Behavior, Volume 16, Issue 4, April 2026.
Parasitic infections like schistosomiasis, soil‐transmitted helminths, and malaria can impair nutrient absorption, oxygen supply, and brain function, leading to memory deficits, attention deficits, reduced intelligence quotient, weak academic performance, and motor or executive deficits.

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, Volume 101, Issue 2, Page 751-803, April 2026.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Resurrecting the Activity of the RNA Subunit of Human RNase P

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
The catalytic RNA (H1 RNA) of the human nuclear tRNA processing enzyme RNase P has >105‐fold lower activity in the absence of its 11 protein cofactors than bacterial RNase P RNAs. By introducing mutations toward the bacterial consensus into its catalytic domain, a two and fivefold activity enhancement could be achieved by changes in the P4‐19/4 region ...
