Utility of Thrombopoietin Receptor Agonists (TPO-RAs) for Prolonged Thrombocytopenia After CAR-T Cell Therapy.

Background: Chimeric Antigen Receptor T-cell (CAR-T) therapy has revolutionized the treatment landscape for various hematological malignancies. However, it is associated with a range of hematologic complications, including severe and often prolonged thrombocytopenia. Currently, there are no known effective preventative or management measures against CAR-T-induced thrombocytopenia.

A conserved chaperone protein is required for the formation of a non-canonical type VI secretion system spike tip complex.

Type VI secretion systems (T6SS) are dynamic protein nanomachines found in Gram-negative bacteria that deliver toxic effector proteins into target cells in a contact-dependent manner. Prior to secretion, many T6SS effector proteins require chaperones and/or accessory proteins for proper loading onto the structural components of the T6SS apparatus. However, despite their established importance, the precise molecular function of several T6SS accessory protein families remains unclear.

A novel FOXM1-BCL2A1 axis determines unfavourable response to venetoclax in AML.

Forkhead box M1 (FOXM1), a Forkhead family transcription factor, is often overexpressed in a variety of human cancers, including AML and strongly associated with therapy resistance and unfavourable outcomes. In AML with NPM1 mutations NPM1/FOXM1 complex sequesters FOXM1 in the cytoplasm and confers favourable treatment outcomes for AML patients, because of FOXM1 inactivation. Inhibition of FOXM1 in AML cell lines and animal models of AML sensitizes AML cells to the Bcl2-inhibitor, venetoclax.

This study aimed to express, purify, and identify recombinant cSP-A1 (RcSP-A1), investigate its effects on chicken macrophage HD11 cells, and evaluate its ability to regulate the LPS-induced inflammatory response.

Knockout or treatment with an antagonist of formyl peptide receptor 1 protects mice from sepsis by inhibiting inflammation.

Background: Sepsis is an infection-related systemic inflammation with high mortality rates. Activation of formyl peptide receptor 1 (FPR1) in immune cells can promote their chemotaxis and inflammatory response, which imbalances immune response during the process of sepsis. FPR1 blockade did diminish systemic inflammatory response during bacterial infection.

Transforming growth factor beta induces interleukin-11 expression in osteoarthritis.

Interleukin-11 (IL-11) is a member of the IL-6 family of cytokines and possesses both pro- and anti-inflammatory properties. IL-11 activates its target cells via binding to a membrane-bound IL-11R and subsequent formation of a homodimer of the signal-transducing receptor gp130. Thus, the expression pattern of the IL-11R determines which cells can be activated by IL-11.

Antheraea pernyi silk nanofibrils with inherent RGD motifs accelerate diabetic wound healing: A novel drug-free strategy to promote hemostasis, regulate immunity and improve re-epithelization.

The chronic inflammation and matrix metalloprotease (MMP)-induced tissue degradation significantly disrupt re-epithelization and delay the healing process of diabetic wounds. To address these issues, we produced nanofibrils from Antheraea pernyi (Ap) silk fibers via a facile and green treatment of swelling and shearing. The integrin receptors on the cytomembrane could specifically bind to the Ap nanofibrils (ApNFs) due to their inherent Arg-Gly-Asp (RGD) motifs, which activated platelets to accelerate coagulation and promoted fibroblast migration, adhesion and spreading.

Chlorpheniramine maleate exerts an anti-keloid activity by regulation of IL-6/JAK1/STAT3 signaling pathway.

Keloids are abnormal scars formed due to fibroblast dysfunction and excessively deposited extracellular matrix (ECM). Despite the unclear process leading to the occurrence of keloids, several studies have demonstrated that histamine and its H1 receptor can effectively regulate fibroblast functions, contributing to keloid formation. Chlorpheniramine maleate (CPM) as a first-generation H1 antihistamine has been widely applied in symptomatic treatment of allergic conditions but its effects on keloids are unknown.

Clinical risk factors for mortality in low severity acute epidural hematoma.

Background: Epidural hematomas (EDH) pose life-threatening risks with considerable morbidity and mortality if left untreated. The prognosis for patients with low-severity acute EDH managed conservatively is variable, with limited understanding of risk factors. This study aims to identify clinical risk factors for mortality in low-severity acute epidural hematoma patients managed conservatively, helping clinicians recognize cases where deviation from conservative management may be necessary.

Noncanonical inhibition of topoisomerase II alpha by oxidative stress metabolites.

During its catalytic cycle, the homodimeric ATPase topoisomerase II alpha (TOP2A) cleaves double stranded DNA and remains covalently bound to 5' ends via tyrosine phosphodiester bonds. After passing a second, intact duplex through, TOP2A rejoins the break and releases from the DNA. Thereby, TOP2A can relieve strain accumulated during transcription, replication and chromatin remodeling and disentangle sister chromatids for mitosis.
