Here we show that mouse IgG2a and IgG1 antibodies specific for the commensal cross-react with pathogen serotypes 2 and 4, although the cross-reactivity conferred by IgG2a is stronger than that by IgG1 antibodies. These findings may be important for understanding the -induced IgG isotype responses and have consequences for the development of an effective pneumococcal vaccine.

The coronavirus disease 2019 (COVID-19) is a fatal disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). To date, several vaccines have been developed to combat the spread of this virus. Mucosal vaccines using food-grade bacteria, such as Lactobacillus spp.

The case report presents a male patient in his mid-60s with a history of hypertension, benign prostatic hyperplasia and chronic kidney disease (CKD). He presented with gradually increasing serum creatinine levels and hyperglobulinemia, leading to suspicion of multiple myeloma. However, subsequent testing revealed features consistent with systemic lupus erythematosus (SLE) and IgG4-related kidney disease (IgG4-RKD).

Acute hepatitis E infection could induce severe outcomes among chronic hepatitis B (CHB) patients. Between 2016 and 2017, an open-label study was conducted to evaluate the immunogenicity and safety of hepatitis E vaccine (HepE) in CHB patients, using healthy adults as parallel controls in China. Eligible participants who were aged ≥30 y were enrolled in the study.

Prebiotics and probiotics have key roles in the intervention and treatment of food allergies. This study assesses the effect of synergistic fructo-oligosaccharide (Lp-FOS) intervention using an allergic mouse model induced by soy protein. The results showed that Lp synergistic FOS significantly decreased clinical allergy scores, inhibited specific antibodies (IgE, IgG, and IgG1), IL-4, IL-6, and IL-17A levels, and increased IFN-γ and IL-10 levels.

Extracellular vesicles (EVs) from can elicit immune responses, positioning them as promising acellular vaccine candidates. We characterized EVs from an avirulent cell wall mutant (Δ) and evaluated their protective potential against invasive candidiasis. EVs from the yeast (YEVs) and hyphal (HEVs) forms of the SC5314 wild-type strain were also tested, yielding high survival rates with SC5314 YEV (91%) and YEV immunization (64%).
