Single-cell analysis of neoplastic plasma cells identifies myeloma pathobiology mediators and potential targets.

Multiple myeloma is a clonal plasma cell (PC) dyscrasia that arises from precursors and has been studied utilizing approaches focused on CD138 cells. By combining single-cell RNA sequencing (scRNA-seq) with scB-cell receptor sequencing (scBCR-seq), we differentiate monoclonal/neoplastic from polyclonal/normal PCs and find more dysregulated genes, especially in precursor patients, than we would have by analyzing bulk PCs. To determine whether this approach can identify oncogenes that contribute to disease pathobiology, mitotic arrest deficient-2 like-1 (MAD2L1) and S-adenosylmethionine synthase isoform type-2 (MAT2A) are validated as targets with drug-like molecules that suppress myeloma growth in preclinical models.

Novel T Cell reactivities to Hybrid Insulin Peptides in Islet Autoantibody-Positive At-Risk Subjects.

Type 1 Diabetes (T1D) is an autoimmune disease mediated by autoreactive T cells. Our studies indicate that CD4 T cells reactive to Hybrid Insulin Peptides (HIPs) play a critical role in T cell-mediated beta-cell destruction. We have shown that HIPs form in human islets between fragments of the C-peptide and cleavage products of secretory granule proteins.

Behavior modeling for a new flexure-based mechanism by Hunger Game Search and physics-guided artificial neural network.

Compliant mechanism has some advantages and has been widely applied in many accurate positioning systems. However, modeling the compliant mechanism behavior has suffered from many challenges, such as unstable results, and the limitation of training data set. In the field of compliant mechanism modeling, there has been no research interested in applying meta-heuristics optimization algorithms to optimize the weights and biases of the neural network globally.

Nanoplastic-induced antibody liquid-liquid phase separation: Insights into potential immunotoxic implications.

The increasing environmental prevalence of micro/nano plastics (MNPs) has raised significant concerns regarding their potential impact on human health, particularly in terms of immunotoxicity. However, the direct effects of MNPs on immune molecules, especially how they may influence protein liquid-liquid phase separation (LLPS)-a critical process implicated in various aspects of immune function-remain largely unexplored. This study addresses this gap by investigating the effects of polystyrene nanoparticles (PS NPs) with different surface modifications and sizes on LLPS in immunoglobulin Y (IgY) antibodies, critical components of the avian immune system.

A novel and quick egg yolk immunoglobulin y antibody extraction method leveraging the protein liquid-liquid phase separation principle.

This study presents a novel and efficient method for extracting immunoglobulin Y (IgY) antibodies from egg yolk based on the principle of liquid-liquid phase separation (LLPS) induced by polyethylene glycol 8000 (PEG 8000). Initial delipidation of egg yolk samples with varying PEG 8000 concentrations demonstrated optimal delipidation efficiency and protein recovery at 2.5 % PEG 8000 concentration.
