Axon Initial Segment: Structure, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 4, April 2026.
The axon initial segment (AIS) is a specialized axonal domain critical for maintaining neuronal polarity, action potential initiation, and network stability. This review summarizes the necessary elements for maintaining AIS structure and plasticity, discussing crucial biological functions of AIS in neuronal signaling and the neural circuit homeostasis,

Dynamic Lysine Acetylation Disrupts Isocitrate Lyase Function and Enables Metabolic Optimisation

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Acetyl‐phosphate–dependent acetylation of E. coli isocitrate lyase (ICL) at K13 and K308 inhibits its activity, while CobB‐mediated deacetylation restores function. Introducing K13R/K308R mutations enhances metabolic balance and increases lycopene yield by 61%, providing a promising approach to optimise microbial cell factories through natural ...

Fast and Simple Series Resistance Imaging for Tandem Solar Cells Using Differential Luminescence

Solar RRL, Volume 10, Issue 6, 29 March 2026.
This article presents a method for imaging the series resistance of subcells in a multijunction device. It requires few input properties, no current or voltage calibration and only three measured images. Validated on single junction and multijunction perovskite‐based devices, this method provides a practical tool for advancing photovoltaic research and

When Are Capacitance–Voltage, Drive‐Level Capacitance Profiling, and Fast‐CV Actually Insensitive to Interface and Bulk Defects?

Solar RRL, Volume 10, Issue 6, 29 March 2026.
Capacitance‐based techniques are widely applied to profile doping in one‐sided semiconductor junctions, yet defect states can distort interpretation. Time‐dependent simulations compare capacitance–voltage, drive‐level capacitance profiling, and Fast‐CV, revealing their sensitivity to trap dynamics and providing guidance for interpreting capacitance ...
