Clinical, genomic, and histopathologic diversity in cerebral cavernous malformations.

Cerebral cavernous malformations (CCMs) are hemorrhagic vascular disorders with varied clinical and radiological presentations, occurring sporadically due to MAP3K3 or PIK3CA mutations or through inherited germline mutations of CCM genes. This study aimed to clarify the clinical, genetic, and pathological features of CCMs using a multicenter cohort across three Chinese centers. We analyzed 290 surgical specimens from symptomatic CCM patients, utilizing whole-exome sequencing, droplet digital PCR, and targeted panel sequencing, alongside immunohistology to examine genotypic and phenotypic differences.

Regulatory T cells in skeletal muscle repair and regeneration: recent insights.

Skeletal muscle repair and regeneration after injury is a multi-stage process, involving a dynamic inflammatory microenvironment consisting of a complex network formed by the interaction of immune cells and their secreted cytokines. The homeostasis of the inflammatory microenvironment determines whether skeletal muscle repair tissues will ultimately form scar tissue or regenerative tissue. Regulatory T cells (Tregs) regulate homeostasis within the immune system and self-immune tolerance, and play a crucial role in skeletal muscle repair and regeneration.

fusion lung adenosquamous carcinoma patient with short-term clinical benefit after crizotinib treatment: a case report.

rearrangements are validated drivers in non-small cell lung cancer (NSCLC), and occur at an extremely low rate in rare pathological subtypes such as adenosquamous carcinoma (ASC). Crizotinib is known to be effective in patients with -rearranged NSCLC. However, the efficacy of crizotinib in patients with -rearranged lung ASC is unknown.
