Sphingolipids, first discovered in 1874 by Johann Thudicum, are among the eight recognized classes of lipids and are present in essentially all plants, animals, and fungi, as well as some viruses and prokaryotes. In mammals, sphingolipids are enriche...
Progesterone (P4) regulates diverse reproductive processes across vertebrates through nuclear receptors; however, its mechanisms in squamate reptiles—particularly in viviparous species—remain poorly understood. In Squamata, P4 primarily a...
Background: Three-finger toxins (3FTxs) are a major axis of functional diversification in advanced snake venoms, with canonical paralytic activity mediated through muscle-type nicotinic acetylcholine receptors (nAChRs) and a broader set of non-nicoti...
Background: Transmissible gastroenteritis virus (TGEV), a coronavirus (CoV) infecting pigs, uses its spike (S) glycoprotein to bind porcine aminopeptidase N (pAPN) for cell entry. Although structural studies have identified receptor-binding motifs (R...
Multipotent mesenchymal stromal stem cells have captivated the scientific community in recent years due to their ability to differentiate into multiple adult cell types. Central to this potential are many members of the nuclear hormone receptor super...
The Hedgehog (Hh) signaling pathway regulates key cellular processes, such as proliferation, differentiation, and morphogenesis. Although its canonical activation involves ligand binding to PTCH1, which activates Smoothened (SMO), noncanonical featur...
Nuclear receptors (NRs) are ligand-activated transcription factors that mediate diverse cellular processes, including signalling, survival, proliferation, immune response and metabolism, through both genomic and non-genomic mechanisms in response to...
Astrocytes are increasingly recognized as active participants of synaptic communication, yet their role in the basal ganglia circuitry remains poorly defined. Emerging evidence indicates that astrocytes in this region express a diverse array of neuro...
Background: The insulin-like growth factor 2 receptor (IGF-2R), also known as the cation-independent mannose 6-phosphate receptor (CI-M6PR), is emerging as a critical receptor for brain function and disease. IGF-2R, in fact, plays a key role in long-...
