Article Synopsis
  • The study investigates pyroptosis, a form of programmed cell death, in the context of status epilepticus (SE), a condition marked by prolonged seizures, and how it relates to neurodegeneration.
  • Researchers induced SE in mice using pilocarpine and found increased levels of inflammatory markers and TRPM7 expression, identifying TRPM7 as a key player in neuronal damage and hyperexcitability.
  • The findings suggest that targeting TRPM7 and NLRP3 could be a potential treatment strategy for SE, as inhibiting these pathways alleviated neuronal hyperexcitability and pyroptosis.

Article Synopsis
  • Post-recanalization target vessel re-occlusion (TVR) is a known complication after endovascular thrombectomy (EVT), linked to poor long-term outcomes, but its causes and incidence right after the procedure are not well understood.
  • A multicenter study examined 167 patients undergoing EVT for large vessel occlusion, measuring changes in the TICI score immediately after the procedure and 10 minutes later, revealing that 16.2% experienced a score change, with 70% of those worsening.
  • The study suggests that neurointerventionalists should conduct angiographic assessments 10 minutes post-EVT to better manage the risk of TVR, considering that only 31% of the entire cohort achieved functional independence at

Genetic evidence against involvement of TRPC proteins in SOCE, ROCE, and CRAC channel function.

Proc Natl Acad Sci U S A

December 2024

Institute of Biomedical Research, School of Biomedical Sciences, Catholic University of Argentina, Buenos Aires C1107AFF, Argentina.

Article Synopsis
  • Researchers used genetically engineered mice and cell lines to study how the depletion of endoplasmic reticulum (ER) calcium stores activates specific calcium entry channels (SOCE) that primarily rely on Orai1 molecules.
  • They discovered that Orai1 is the dominant calcium entry pathway compared to Orai2 and Orai3, and this process does not require functional TRPC molecules, as shown by experiments using cells with inactive TRPC genes.
  • The study also found that even though the TRPC genes were disrupted, both store-depletion-activated calcium entry and receptor-operated calcium entry (ROCE) still relied on Orai1, leading to the establishment of a new strain of mice called TRPC heptaKO mice, which are

Aims: Continued low mortality from coronary heart disease in Japan, despite deleterious changes in traditional risk factors, remains unexplained. Since aortic calcification (AC) was an early predictor of cardiovascular mortality, we compared the progression and incidence of AC between Japanese in Japan, white Americans, and third-generation Japanese Americans in the ERA JUMP cohort. We examined whether higher blood levels of marine-derived n-3 fatty acids (FAs) in Japanese than in Americans accounted for the difference.

Purpose Of Review: The most common four neurodegenerative atypical parkinsonian disorders (APDs) are progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal syndrome (CBS), and dementia with Lewy bodies (DLB). Their formal diagnostic criteria often require subspecialty experience to implement as designed and all require excluding competing diagnoses without clearly specifying how to do that. Validated diagnostic criteria are not available at all for many of the other common APDs, including normal pressure hydrocephalus (NPH), vascular parkinsonism (VP), or drug-induced parkinsonism (DIP).
