A prevalent observation in high-throughput screening and drug discovery programs is the inhibition of protein function by small-molecule compound aggregation. Here, we present the X-ray structural description of aggregation-based inhibition of a protein-protein interaction involving tumor necrosis factor α (TNFα). An ordered conglomerate of an aggregating small-molecule inhibitor (JNJ525) induces a quaternary structure switch of TNFα that inhibits the protein-protein interaction between TNFα and TNFα receptors. SPD-304 may employ a similar mechanism of inhibition.

Microglia, the resident immune cells of the central nervous system (CNS), are involved in the pathogenesis of neurodegenerative diseases, such as Alzheimer's disease (AD), Dementia with Lewy Bodies (DLB), and Parkinson's disease (PD). 14-3-3 proteins act as molecular hubs to regulate protein-protein interactions, which are involved in numerous cellular functions, including cellular signaling, protein folding, and apoptosis. We previously revealed decreased 14-3-3 levels in the brains of human subjects with neurodegenerative diseases.

Objective: Cisplatin-induced acute kidney injury (Cis-AKI) is a significant cause of renal damage, characterized by tubular injury, ferroptosis, and oxidative stress. While therapeutic options for Cis-AKI remain limited, identifying novel targets to prevent kidney injury is critical. This study focuses on GALNT14, a gene associated with ferroptosis, and its potential role in mitigating Cis-AKI.

This study investigates the effects of L-carnitine on nuclear maturation and fertilization in cattle and goat oocytes. Ovaries were collected from females with poor reproductive efficiency in the tropical climate, and cumulus-oocyte complexes (COCs) were retrieved from large antral follicles. COCs were cultured with varying concentrations of L-carnitine (0, 0.

Plasmablastic lymphoma (PBL) is a rare and aggressive non-Hodgkin lymphoma with a poor prognosis and short survival rates. It is classified as a large B-cell lymphoma subtype, but carries a plasmacytic immunophenotype. Therefore, PBL has pathogenetic overlaps with diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS) and plasma cell neoplasms (PCNs).

Background: The proteome is a valuable resource for pinpointing therapeutic targets. Therefore, we conducted a proteome-wide Mendelian randomization (MR) study aimed at identifying potential protein markers and therapeutic targets for Anti-N-Methyl-D-Aspartate Receptor Encephalitis (NMDAR-E).
Methods: Protein quantitative trait loci (pQTLs) were obtained from seven published genome-wide association studies (GWASs) focusing on the plasma proteome, resulting in summary-level data for 734 circulating protein markers.
