Summary: Fibrotic scars caused by spinal cord injury hinder neuronal regeneration, resulting in paralysis. The role of astrocytes in fibrotic scar formation is not well understood. This study showed that astrocytic Cebpd promotes fibroblast migration and fibrotic scar formation through the Ptx3/NF kappa B/Mmp3 axis pathway. The RI37 peptide was identified as a potential therapeutic agent to inhibit fibrotic scar formation.

Summary: The study found that the expression of PDGFD and PDGFB gradually increased after spinal cord injury (SCI). PDGFB was mainly secreted by astrocytes, while PDGFD was mainly secreted by macrophages/microglia and fibroblasts. Activation of the PDGFR beta pathway can directly induce fibrotic scar formation. Specific blockade of this pathway contributes to the treatment of SCI.

Summary: Spinal cord injury often results in permanent disability due to the loss of functional recovery. The formation of a glial scar around the damaged tissue can interrupt the healing process, and therapeutic treatments targeting scar components are important for improving functional recovery.

Summary: Spinal cord injury (SCI) affects millions of people, mainly young individuals, causing deficits in sensory, motor, and autonomic functions. Regrowth of axons is a crucial goal for neurological recovery after SCI, but is challenging due to the formation of a glial scar. Traditionally considered detrimental, recent evidence suggests that glial scars are beneficial for surrounding spared tissue. Experimental studies in rodent models have shown that removal of specific glial cell populations disrupts scar organization, increases inflammation, extends tissue degeneration, and impairs recovery after SCI.

Summary: Traumatic spinal cord injury (SCI) causes physical impairment and psychological devastation through complex pathological processes. The two phases of SCI include primary mechanical damage and secondary injury, which lead to vascular disruption, inflammation, cell death, and scar formation. Secretory factors, such as neurotrophic factors and growth factors, play important roles in nerve regeneration, while the blood-spinal cord barrier (BSCB) is damaged, allowing immune cell infiltration and promoting angiogenesis. This review discusses the therapeutic application and outcomes of these secretory factors in SCI.

Summary: This study investigated the effect of apigenin on fibrous scar formation after spinal cord injury (SCI) in mice. Results showed that apigenin inhibited fibrous scar formation and promoted motor function recovery. It achieved this by reducing the expression of fibrosis-related factors through the TGF beta/SMADs signaling pathway.

Summary: D-DT is a novel proinflammatory mediator of reactive astrocytes after spinal cord injury, which can activate multiple signal pathways of astrocytes and induce the production of inflammatory cytokines through interaction with CD74 receptor. Inhibition of D-DT can attenuate NF-kappa B activation, reduce the levels of inflammatory cytokines, and improve locomotor function recovery.

Summary: Recognizing the crucial role of the immune microenvironment in tumor progression is key to identifying immunotherapeutic targets. This study explores the potential impact of GARP on regulating survival and tumor-infiltrating T-cells in gastric cancer. The upregulation of GARP was associated with increased Treg and CD4+ T cell infiltration, as well as positive relationships with immune checkpoint expression in the TME of gastric cancer. Cox regression analysis highlighted the predictive value of GARP or GARP+CD4+ T cell on overall survival probability.

Summary: This study found that the expression of KLHDC8A was higher in glioma tissues and was associated with patient clinical characteristics. Gliomas exhibited an immune characteristic with high abundance of macrophages, neutrophils, regulatory T cells, and immune checkpoint PD-L1 expression. KLHDC8A+CD68+ macrophages and KLHDC8A were predictive of unfavorable survival in glioma patients.
