Article Abstract
The canonical function of caspase-8 is to control timely cellular apoptosis to maintain tissue homeostasis and clear dysfunctional cells; however, emerging findings reveal novel, non-canonical roles of caspase in addition to regulating cellular apoptosis, including inflammatory response regulation, immune function, and cell differentiation. Furthermore, the functional versatility of caspase-8 is reported to be contingent on the presence and dimerization of various isoforms, which are produced through alternative splicing, altering its function and protein-protein interactions. Equally important are post-translational modifications, including phosphorylation and ubiquitination, which can act as a nexus to control caspase-8 activity and cellular localization. Here, we review the alternative splicing and post-translational modifications made to caspase-8 and discuss their influence on its canonical and non-canonical roles.

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.
