Platelets and platelet enriched products have been widely studied for their roles in promoting cell proliferation, migration, and tissue regeneration, making them highly interesting for clinical applications such as traumatology, dental, orthopaedic, and plastic surgery. However, their clinical adoption remains limited, partly due to fragmented and inconsistent data. Previous reviews have explored various applications of PRP therapies, but no comprehensive work has systematically mapped their processing methods, treatment modalities, and applications alongside clinical outcomes.

Tumor-associated microglia and blood-derived macrophages (TAMs) play a central role in modulating the immune suppressive microenvironment in glioma. Here, we show that GPNMB is predominantly expressed by TAMs in human glioblastoma multiforme and the murine RCAS-PDGFb high grade glioma model. Loss of GPNMB in the in vivo tumor microenvironment results in significantly smaller tumor volumes and generates a pro-inflammatory innate and adaptive immune cell microenvironment.

Neurofibromatosis type 1 (NF1) is an autosomal dominant condition caused by germline mutations in the neurofibromin 1 (NF1) gene. Children with NF1 are prone to the development of multiple nervous system abnormalities, including autism and brain tumors, which could reflect the effect of NF1 mutation on microglia function. Using heterozygous Nf1-mutant mice, we previously demonstrated that impaired purinergic signaling underlies deficits in microglia process extension and phagocytosis in situ.

: Neurosurgery has been underrepresented in the medical school curriculum. Advances in augmented reality and 3D printing have opened the way for early practical training through simulations. We assessed the usability of the UpSurgeOn simulation-based training model and report first experiences from a hands-on neurosurgery course for medical students.

Article Synopsis
  • Chronic Kidney Disease (CKD) leads to an inflammatory immune response, which is linked to hypertension and cardiovascular issues, potentially due to imbalances in gut bacteria (dysbiosis).
  • In a study of 48 children at varying stages of CKD, researchers found signs of inflammation, gut dysfunction, and changes in the gut microbiome, including reduced production of beneficial compounds like short-chain fatty acids.
  • The findings suggest that disruptions in gut health and microbial metabolites contribute to an inflammatory immune response in CKD, indicating the significant role of the microbiome in influencing kidney health and associated cardiovascular risks.

Article Synopsis
  • Researchers found that a substance called CCL18 from special brain cells called GAMs helps glioblastoma multiforme (a type of brain cancer) to grow and spread.
  • They created a way to study CCL18 using human brain cells in mice to see how it works, since it’s not found in mouse cells.
  • They discovered that CCL18 helps glioma cells grow by using a specific receptor (CCR8) and acts through another molecule (ACP5) to cause this growth.

Microglia are the primary immune-competent cells of the central nervous system (CNS) and sense both pathogen- and host-derived factors through several receptor systems including the Toll-like receptor (TLR) family. Although TLR5 has previously been implicated in different CNS disorders including neurodegenerative diseases, its mode of action in the brain remained largely unexplored. We sought to determine the expression and functional consequences of TLR5 activation in the CNS.
