Formation of BCR Oligomers Provides a Mechanism for B cell Affinity Discrimination [PDF]

arXiv, 2012
B cells encounter antigen over a wide affinity range. The strength of B cell signaling in response to antigen increases with affinity, a process known as "affinity discrimination". In this work, we use a computational simulation of B cell surface dynamics and signaling to show that affinity discrimination can arise from the formation of BCR oligomers ...

Osteopenic occult vertebral fracture is associated with poor oncological outcome in patients with hepatocellular carcinoma after hepatic resection

Annals of Gastroenterological Surgery, EarlyView.
Osteopenic occult vertebral fracture (OVF) was associated with poor long‐term outcomes in patients with HCC after hepatic resection. Osteopenic OVF had a poorer prognosis than that of patients with either osteopenia or OVF. Abstract Background Although osteopenia has been associated with poor outcomes in patients with hepatocellular carcinoma (HCC ...

Integrating influenza antigenic dynamics with molecular evolution [PDF]

arXiv, 2013
Influenza viruses undergo continual antigenic evolution allowing mutant viruses to evade host immunity acquired to previous virus strains. Antigenic phenotype is often assessed through pairwise measurement of cross-reactivity between influenza strains using the hemagglutination inhibition (HI) assay.

A dynamical model of the adaptive immune system: effects of cells promiscuity, antigens and B-B interactions [PDF]

, 2015
We analyse a minimal model for the primary response in the adaptive immune system comprising three different players: antigens, T and B cells. We assume B-T interactions to be diluted and sampled locally from heterogeneous degree distributions, which mimic B cells receptors' promiscuity.

Evaluating Zero-Shot Scoring for In Vitro Antibody Binding Prediction with Experimental Validation [PDF]

arXiv, 2023
The success of therapeutic antibodies relies on their ability to selectively bind antigens. AI-based antibody design protocols have shown promise in generating epitope-specific designs. Many of these protocols use an inverse folding step to generate diverse sequences given a backbone structure.

FIB‐3 index as a novel age‐independent predictor of liver fibrosis and prognosis in hepatocellular carcinoma patients undergoing hepatectomy

Annals of Gastroenterological Surgery, EarlyView.
Fibrosis‐3 index (FIB‐3) can stratify the risk of the survival and the recurrence‐free survival. The FIB‐3 index is a reliable, age‐independent tool for assessing liver fibrosis and prognosis in HCC patients post‐hepatectomy. Its use may improve clinical outcomes and support personalized treatment strategies. Abstract Background Liver fibrosis is a key

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.
