Mechanisms of spinal glial activation in chemotherapy‐induced peripheral neuropathy: Focus on microglia and astrocytes

Ibrain, Volume 12, Issue 1, Page 65-85, Spring 2026.
Chemotherapy‐induced peripheral neuropathy (CIPN) remains a major clinical challenge, with central sensitization considered an important pathological mechanism in its occurrence and persistence. This review focuses on spinal astrocytes and microglia, systematically summarizing the pathological mechanisms of spinal glial cells involved in CIPN caused by

Engineered biosynthesis of bacteriochlorophyll gF in Rhodobacter sphaeroides

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2018
Engineering photosynthetic bacteria to utilize a heterologous reaction center that contains a different (bacterio) chlorophyll could improve solar energy conversion efficiency by allowing cells to absorb a broader range of the solar spectrum. One promising candidate is the homodimeric type I reaction center from Heliobacterium modesticaldum.

Precise regulating the specific oxygen consumption rate to strengthen the CoQ10 biosynthesis by Rhodobater sphaeroides

Bioresources and Bioprocessing
Coenzyme Q10 (CoQ10) is the most consumed dietary supplement and mainly biosynthesized by aerobic fermentation of Rhodobacter sphaeroides (R. sphaeroides). Oxygen supply was identified as a bottleneck for improving CoQ10 yield in R. sphaeroides.

Enhancing polyphenol synthesis and antioxidant activity in Camellia sinensis using shikimic and salicylic acids

JSFA reports, Volume 6, Issue 3, Page 73-87, March 2026.
Abstract Background Camellia sinensis, widely consumed as tea, is the second most popular beverage globally and is valued for its health benefits. However, environmental stressors pose a significant challenge to the tea industry. This study investigates the potential of shikimic acid (ShA) and its derivative, salicylic acid (SA), as inducers to enhance

Cardiolipin increases in chromatophores isolated from Rhodobacter sphaeroides after osmotic stress: structural and functional roles

Journal of Lipid Research, 2009
Chromatophores isolated from cells of Rhodobacter sphaeroides exposed to hypertonic solutions were enriched in cardiolipin (CL). Because CL levels are raised by increasing the incubation time of R.

Synthetic Cells on Demand: From Molecular Stimuli to Cellular Functions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
ABSTRACT Synthetic cells constructed via bottom‐up approaches using lipid or polymer vesicles have become essential tools for mimicking cellular functions and studying synthetic biological systems. These vesicles can undergo morphological changes and trigger internal reactions in response to external stimuli, such as osmotic pressure, temperature, pH ...

Characterization of Polyhydroxyalkanoates Produced by Rhodobacter sphaeroides ADZ101

Baghdad Journal of Biochemistry and Applied Biological Sciences
Background: Polyhdroxyalkanoate (PHA) is a biopolymer synthesized by some bacteria as a carbon and energy storage. It has similar characteristics to fossil-derived plastic. Hence, it is considered a replacement for nonbiodegradable plastic.

The bacterial RNA polymerase-associated CarD protein couples promoter activity to DNA supercoiling

Nature Communications
RNA polymerase (RNAP) must unwind duplex DNA prior to transcription initiation. In bacteria, unwinding starts at a DNA motif called the promoter −10 element. Specifically, non-template strand bases interact with RNAP to trigger the process.

Photosynthetic apparatus of Rhodobacter sphaeroides exhibits prolonged charge storage

Nature Communications, 2019
Photosynthetic proteins are used to harvest solar energy in bio-photovoltaics, but are typically not investigated for charge storage. Here the authors report prolonged charge storage in multilayers of photoproteins as well as a proof-of-principle ...
