Succinylation of SERCA2a at K352 Promotes Its Ubiquitinoylation and Degradation by Proteasomes in Sepsis-Induced Heart Dysfunction.

Background: Intracellular Ca cycling governs effective myocardial systolic contraction and diastolic relaxation. SERCA2a (sarco/endoplasmic reticulum Ca ATPase type 2a), which plays a crucial role in controlling intracellular Ca signaling and myocardial cell function, is downregulated and inactivated during sepsis-induced heart dysfunction. However, the cause of this dysregulation remains unclear.

Type 2 immunity in allergic diseases.

Significant advancements have been made in understanding the cellular and molecular mechanisms of type 2 immunity in allergic diseases such as asthma, allergic rhinitis, chronic rhinosinusitis, eosinophilic esophagitis (EoE), food and drug allergies, and atopic dermatitis (AD). Type 2 immunity has evolved to protect against parasitic diseases and toxins, plays a role in the expulsion of parasites and larvae from inner tissues to the lumen and outside the body, maintains microbe-rich skin and mucosal epithelial barriers and counterbalances the type 1 immune response and its destructive effects. During the development of a type 2 immune response, an innate immune response initiates starting from epithelial cells and innate lymphoid cells (ILCs), including dendritic cells and macrophages, and translates to adaptive T and B-cell immunity, particularly IgE antibody production.

It aimed to examine the associations of triglyceride-glucose (TyG) index, metabolic score for insulin resistance (METS-IR), estimated glucose disposal rate (eGDR) and with long-term deficit-accumulation frailty trajectories and physical function decline.

Methods: Data from 6722 participants in the China Health and Retirement Longitudinal Study (CHARLS) were analyzed.

Open frameworks in the NaMn(PO)F fluoro-pyrophosphates system.

Three new sodium manganese fluoro-pyrophosphate compounds, namely, NaMn(PO)F (I), NaMn(PO)F (II), and NaMn(PO)F (III), have been synthesized by heating a mixture of NaPF, NaPOF or NaHPO with different Mn sources in NaNO and KNO fluxes. The structures of the title compounds were characterized single-crystal X-ray diffraction (XRD). II is characteristic of a shell of Na ions that encloses one [Mn(PO)F] unit, whereas I and III reveal three-dimensional (3D) frameworks that consist of MnO, Mn/NaOF octahedra or MnO octahedra and distorted MnO square pyramids with PO units, where Na cations reside in different-membered ring one-dimensional (1D) tunnels.

Specifically blocking αvβ8-mediated TGF-β signaling to reverse immunosuppression by modulating macrophage polarization.

Background: Targeting the TGF-β pathway in tumor therapy has proven challenging due to the highly context-dependent functions of TGF-β. Integrin αvβ8, a pivotal activator of TGF-β, has been implicated in TGF-β signaling within tumors, as demonstrated by the significant anti-tumor effects of anti-αvβ8 antibodies. Nevertheless, the expression profile of αvβ8 remains a subject of debate, and the precise mechanisms underlying the anti-tumor effects of anti-αvβ8 antibodies are not yet fully elucidated.

ROS scavenging and corneal epithelial wound healing by a self-crosslinked tissue-adhesive hydrogel based-on dual-functionalized hyaluronic acid.

Reactive oxygen species (ROS) scavenging is a viable approach to promote corneal epithelium wound healing.

Background: The effect of embolization of the middle meningeal artery in patients with subacute or chronic subdural hematoma is uncertain.

Methods: We performed a multicenter, open-label, randomized trial in China, involving patients with symptomatic nonacute subdural hematoma with mass effect. Patients were assigned to undergo burr-hole drainage or receive nonsurgical treatment at the surgeon's discretion, and patients in each group were then randomly assigned, in a 1:1 ratio, to undergo middle meningeal artery embolization with liquid embolic material or to receive usual care.

Glia-like taste cells mediate an intercellular mode of peripheral sweet adaptation.

The sense of taste generally shows diminishing sensitivity to prolonged sweet stimuli, referred to as sweet adaptation. Yet, its mechanistic landscape remains incomplete. Here, we report that glia-like type I cells provide a distinct mode of sweet adaptation via intercellular crosstalk with chemosensory type II cells.

A pan-orthoebolavirus neutralizing antibody encoded by mRNA effectively prevents virus infection.

is a genus of hazardous pathogens that has caused over 30 outbreaks. However, currently approved therapies are limited in scope, as they are only effective against the Ebola virus and lack cross-protection against other orthoebolaviruses. Here, we demonstrate that a previously isolated human-derived antibody, 2G1, can recognize the glycoprotein (GP) of every orthoebolavirus species.
