Optimization of photobiomodulation therapy for spinal cord injury: A review

Photochemistry and Photobiology, EarlyView.
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Semaphorin-3E Produced by Immature Dendritic Cells Regulates Activated Natural Killer Cells Migration

Frontiers in Immunology, 2018
Natural killer (NK) cells and dendritic cells (DCs) are two innate immune cells that are critical in regulating innate and adaptive immunity. Cellular functions and migratory responses of NK or DC can be further regulated in NK-DC crosstalk that involves

Acute pain transfusion reaction in a patient with thalassemia: In‐depth characterization of short‐ and long‐term phenotypes

Transfusion, EarlyView.
Abstract Background Acute pain transfusion reaction (APTR) is a rare, under‐recognized condition of unknown etiology. It can cause significant distress in recipients, necessitating symptomatic management and, occasionally, hospitalization. Study Design and Methods Here, we present an APTR event in an adult subject with transfusion‐dependent thalassemia

New Eukaryotic Semaphorins with Close Homology to Semaphorins of DNA Viruses

Genomics, 1998
Semaphorins were initially described as a family of repulsive guidance molecules in embryonal development. Their basic structure consists of an N-terminal signal sequence, the defining semaphorin domain ofapproximately 500 amino acids, an Ig-like domain,and a variable carboxy-terminus.

Immune plexins and semaphorins: old proteins, new immune functions

, 2013
Plexins and semaphorins are a large family of proteins that are involved in cell movement and response. The importance of plexins and semaphorins has been emphasized by their discovery in many organ systems including the nervous (Nkyimbeng-Takwi and ...

Plasma Membrane Remodeling During Microglial Activation: A Hypothesis Linking Microglial Shape and Lipid Droplet Formation

Glia, Volume 74, Issue 8, August 2026.
Microglial morphology changes in response to damage by Aβ and aging result in significant reductions in cell surface area. Transcriptomic analyses suggest that fatty acid synthesis and triacylglycerol formation drive redistribution of surface membrane into intracellular lipid droplets.

De Novo Genome Assemblies of Four Rainbow Trout Genetic Lines Reveal Structural Variants in Pursuit of a Pangenome Reference

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Rainbow trout (Oncorhynchus mykiss) exhibit extensive genomic diversity shaped by domestication, life history and geographic origin. To advance the development of a comprehensive pangenome reference, we present new de novo genome assemblies of two genetically and ecologically distinct lines: Whale Rock (WR; wild, landlocked, Central California)

Class 3 semaphorin mediates dendrite growth in adult newborn neurons through Cdk5/FAK pathway. [PDF]

PLoS ONE, 2013
Class 3 semaphorins are well-known axonal guidance cues during the embryonic development of mammalian nervous system. However, their activity on postnatally differentiated neurons in neurogenic regions of adult brains has not been characterized. We found

Mical links semaphorins to F-actin disassembly

, 2010
How instructive cues present on the cell surface have their precise effects on the actin cytoskeleton is poorly understood. Semaphorins are one of the largest families of these instructive cues and are widely studied for their effects on cell movement ...
