B-cell acute lymphoblastic leukemia (B-ALL) is a rare malignancy in adults with outcomes remaining poor, especially compared to children. Over the past two decades, extensive whole-genome studies have identified numerous genetic alterations driving leukemia, leading to the recognition of more than 20 distinct subtypes which are closely associated with treatment response and prognosis. In pediatric B-ALL, large correlation studies have made genetic classification a central component of risk-adapted treatment strategies.

Coexistence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) has been observed in some chronic hepatitis B (CHB) patients (DP patients), but the clinical outcomes and comprehensive characterization of immune micro-environmental changes for this specific population remain inconclusive. In this study, we retrospectively analyze the prognosis of 305 patients in Foshan City, Guangdong Province, China, and also investigated the molecular immunology changes in HBsAg and anti-HBs double positive CHB patients (DP group), CHB patients who had recovered from IFN-ɑ treatment (RP group), and healthy controls (HC group) using T cell receptor (TCR) and B cell receptor (BCR) immune repertoire sequencing. Our findings revealed that 22.

Our objective is to determine the protein and complements constituents of Cord blood Platelet-rich plasma (CB-PRP), based on the hypothesis that it contains beneficial components capable of arresting or potentially decelerating the advancement of atrophic age-related macular degeneration (dry-AMD), with the support of radiomics. Two distinct pools of CB-PRP were assessed, each pool obtained from a total of 15 umbilical cord-blood donors. One aliquot of each pool respectively was subjected to proteomic analysis in order to enhance the significance of our findings, by identifying proteins that are shared between the two sample pools and gaining insights into the pathways they are associated with.

The aging process often leads to immune-related diseases, including infections, tumors, and autoimmune disorders. Recently, researchers identified a special subpopulation of B cells in elderly female mice that increases with age and accumulates prematurely in mouse models of autoimmune diseases or viral infections; these B cells are known as age-related B cells (ABCs). These cells possess distinctive cell surface phenotypes and transcriptional characteristics, and the cell population is widely recognized as CD11cCD11bT-betCD21CD23 cells.

Introduction: The coronavirus disease 2019 (COVID-19) global pandemic has been the most severe public health emergency since 2019. Currently, the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the most dominant. The most prominent symptom of SARS-CoV-2 infection is respiratory.
