Loss of Type 2 Bone Morphogenetic Protein Receptor Activates NOD-Like Receptor Family Protein 3/Gasdermin E-Mediated Pyroptosis in Pulmonary Arterial Hypertension.

Background: Pulmonary arterial hypertension (PAH) is an incurable disease initiated by endothelial dysfunction, secondary to vascular inflammation and occlusive pulmonary arterial vascular remodeling, resulting in elevated pulmonary arterial pressure and right heart failure. Previous research has reported that dysfunction of type 2 bone morphogenetic protein receptor (BMPR2) signaling pathway in endothelium is inclined to prompt inflammation in PAH models, but the underlying mechanism of BMPR2 deficiency-mediated inflammation needs further investigation. This study was designed to investigate whether BMPR2 deficiency contributes to pulmonary arterial hypertension via the NLRP3 (NOD-like receptor family protein 3)/GSDME (gasdermin E)-mediated pyroptosis pathway.

Rabies is a serious zoonotic disease caused by the rabies virus (RABV). Despite the successful development of vaccines and efforts made in drug discovery, rabies is incurable. Therefore, development of novel drugs is of interest to the scientific community.

Systemic autoimmune rheumatic diseases (SARDs) consist of a broad range of immune-mediated multisystem diseases. They are chronic, incurable illnesses that often present in early to mid-life and can be associated with a high symptom burden, disability, and early mortality. Treatment guidelines for similar chronic, life-limiting conditions with uncertain disease courses now recommend palliative care (PC) assessment at the time of diagnosis.

The term "low-grade glioma" historically refers to adult diffuse gliomas that exhibit a less aggressive course than the more common high-grade gliomas. In the current molecular era, "low-grade" refers to World Health Organization central nervous system grade 2 gliomas almost always with an isocitrate dehydrogenase (IDH) mutation (astrocytomas and oligodendrogliomas). The term "lower-grade gliomas" has emerged encompassing grades 2 and 3 IDH-mutant astrocytomas and oligodendrogliomas, to acknowledge that histological grade is not as important a prognostic factor as molecular features, and distinguishing them from grade 4 glioblastomas, which lack an IDH mutation.

Chimeric antigen receptor (CAR) T-cell therapy has reshaped the face of cancer treatment, leading to record remission rates in previously incurable hematological cancers. These successes have spurred interest in adapting the CAR platform to a small yet pivotal subset of CD4 T cells primarily responsible for regulating and inhibiting the immune response, regulatory T cells (Tregs). The ability to redirect Tregs' immunosuppressive activity to any extracellular target has enormous implications for creating cell therapies for autoimmune disease, organ transplant rejection, and graft-versus-host disease.
