Article Abstract
In this study we evaluated the percentages of CD3(-)CD56(bright), CD3(-)CD56(dim), CD3(-)CD56(bright)perforin(+) and CD3(-)CD56(dim)perforin(+) Natural Killer (NK) cells in peripheral blood from untreated secondary progressive (SP) and primary progressive (PP) multiple sclerosis (MS) patients and age and sex matched healthy subjects. Both PPMS patients and SPMS patients showed increased percentages of circulating CD3(-)CD56(dim)perforin(+) NK cells than healthy subjects. The increased percentage of CD3(-)CD56(dim) NK cells expressing perforin in patients affected by the progressive forms of MS suggests a possible role of this NK cell subpopulation in the pathogenesis of the disease.

Understanding the genetic causes of diseases affecting pancreatic β cells and neurons can give insights into pathways essential for both cell types. Microcephaly, epilepsy and diabetes syndrome (MEDS) is a congenital disorder with two known aetiological genes, IER3IP1 and YIPF5. Both genes encode proteins involved in endoplasmic reticulum (ER) to Golgi trafficking.

3-O-sulfation of heparan sulfate (HS) is the key determinant for binding and activation of Antithrombin III (AT). This interaction is the basis of heparin treatment to prevent thrombotic events and excess coagulation. Antithrombin-binding HS (HSAT) is expressed in human tissues, but is thought to be expressed in the subendothelial space, mast cells, and follicular fluid.

Neural stem cells (NSCs) are multipotent stem cells with self-renewal capacity, able to differentiate into all neural lineages of the central nervous system, including neurons, oligodendrocytes, and astrocytes; thus, their proliferation and differentiation are essential for embryonic neurodevelopment and adult brain homoeostasis. Dysregulation in these processes is implicated in neurological disorders, highlighting the need to elucidate how NSCs proliferate and differentiate to clarify the mechanisms of neurogenesis and uncover potential therapeutic targets. MicroRNAs (miRNAs) are small, post-transcriptional regulators of gene expression involved in many aspects of nervous system development and function.

Engineering functional exosomes represents a cutting-edge approach in biomedicine, holding the promise to transform targeted therapy. However, challenges such as achieving consistent modification and scalability have limited their wider adoption. Herein, we introduce a universal and effective strategy for engineering multifunctional exosomes through cell fusion.

The β-adrenergic receptor (βAR), a prototype G protein-coupled receptor, controls cardiopulmonary function underpinning O delivery. Abundance of the βAR is canonically regulated by G protein-coupled receptor kinases and β-arrestins, but neither controls constitutive receptor levels, which are dependent on ambient O. Basal βAR expression is instead regulated by the prolyl hydroxylase/pVHL-E3 ubiquitin ligase system, explaining O responsivity.
