HERV-W Env Induces Neuron Pyroptosis via the NLRP3-CASP1-GSDMD Pathway in Recent-Onset Schizophrenia.

Int J Mol Sci

January 2025

State Key Laboratory of Virology and Biosafety, Department of Medical Microbiology, School of Basic Medical Sciences, Wuhan University, Wuhan 430071, China.

HERVs (Human endogenous retroviruses) are remnants of ancient exogenous retroviruses that have integrated into the human genome, particularly in germ-line cells. Among these, the envelope protein gene (Human endogenous retroviruses W family envelope protein), located on chromosome 7 and primarily expressed in the human placenta, has been closely linked to various neuropsychiatric disorders, including schizophrenia, as well as autoimmune diseases and cancer. Recent studies have highlighted the abnormal expression of cytokines as a key factor in the pathophysiology of schizophrenia.

The Molecular Biology of Placental Transport of Calcium to the Human Foetus.

Int J Mol Sci

January 2025

Department of Clinical Biochemistry, University Hospital Southampton NHS Foundation Trust, Southampton General Hospital, Southampton SO16 6YD, UK.

From fertilisation to delivery, calcium must be transported into and within the foetoplacental unit for intracellular signalling. This requires very rapid, precisely located Ca transfers. In addition, from around the eighth week of gestation, increasing amounts of calcium must be routed directly from maternal blood to the foetus for bone mineralisation through a flow-through system, which does not impact the intracellular Ca concentration.
