Oligodendrocyte precursor cell (OPC) maturation requires membrane addition for myelin sheath formation. Since the Rab system has been shown to contribute to membrane addition in other cell types, in this study, we explored the role of Rab in OPC maturation. SiRNA and shRNA techniques and conditional knockout mice provided in vitro and in vivo evidence that Rab10 is involved in OPC maturation and may affect myelination during OPC development.

Article Synopsis
- Wheat is the second-most consumed staple food in India, and rising heat waves have highlighted the need for developing heat-tolerant wheat varieties to ensure food security.
- A study used a mapping population of backcross introgression lines (BILs) derived from a heat-tolerant wild wheat relative to identify quantitative trait loci (QTLs) for traits related to terminal heat tolerance during optimal and heat-stressed conditions.
- The research led to the discovery of 30 QTLs associated with heat tolerance traits on multiple chromosomes, providing valuable insights and potential markers for genomic breeding aimed at improving heat resilience in wheat plants.

Myelin injury occurs in brain ageing and in several neurological diseases. Failure of spontaneous remyelination is attributable to insufficient differentiation of oligodendrocyte precursor cells (OPCs) into mature myelin-forming oligodendrocytes in CNS demyelinated lesions. Emerging evidence suggests that peroxisome proliferator-activated receptor γ (PPARγ) is the master gatekeeper of CNS injury and repair and plays an important regulatory role in various neurodegenerative diseases.

Oligodendrocytes (OLs), the myelin-forming cells of the central nervous system (CNS), develop from OL precursor cells (OPCs) through a complex process involving significant morphological changes that are critically dependent on the dynamic interactions between cytoskeletal networks. Growth arrest-specific 2-like protein 1 (GAS2L1) is a cytoskeletal linker protein that mediates the cross-talk between actin filaments and microtubules. However, its role in OL and myelin development remains unknown.

The current lack of therapeutic approaches to demyelinating disorders and injuries stems from a lack of knowledge surrounding the underlying mechanisms of myelination. This knowledge gap motivates the development of effective models to study the role of environmental cues in oligodendrocyte progenitor cell (OPC) maturation. Such models should focus on determining, which factors influence OPCs to proliferate and differentiate into mature myelinating oligodendrocytes (OLs).

White matter damage and subsequent demyelination significantly contribute to long-term functional impairment after ischaemic stroke. Identifying novel pharmacological targets to restore myelin integrity by promoting the maturation of oligodendrocyte precursor cells (OPCs) into new myelinating oligodendrocytes may open new perspectives for ischaemic stroke treatment. In this respect, previous studies highlighted the role of the G protein-coupled membrane receptor 17 (GPR17) as a key regulator of OPC differentiation in experimental models of brain injury, including ischaemic stroke.
