Opening closed inward rectifier potassium channel doors

British Journal of Pharmacology, Volume 183, Issue 10, Page 2197-2218, May 2026.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Acceptorless Dehydrogenative Polymerization

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Acceptor‐less dehydrogenative polymerization (ADP) enables the atom‐economic step‐growth synthesis of different type of polymers directly from simple alcohols, releasing H2 as the sole by‐product. This review outlines the mechanistic foundations, catalytic systems, and emerging polymer architectures of ADP, highlighting its potential as a sustainable ...

The MdICE1/MdFAMA‐MdTYDC Transcriptional Module Confers Cold Tolerance by Regulating Dopamine Metabolism in Apple

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3012-3031, May 2026.
ABSTRACT Low temperature is a critical abiotic stress that imposes major constraints on the sustainable development of the fruit tree industry. Although exogenous dopamine has been shown to enhance cold tolerance in plants, its molecular mechanisms in apple (Malus domestica) remain poorly understood.

Innate Immunity and Microbial Recognition in Reproduction: From Barrier Defense to Maternal–Fetal Tolerance

The FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Graphical abstract illustrating the barrier defense–tolerance framework of reproductive innate immunity. Across the female and male reproductive tracts and the maternal–fetal interface, epithelial barriers, innate sensors, immune cells, and microbial signals are integrated to preserve reproductive homeostasis.
