Article Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), is modifying human activity all over the world with significant health and economic burden. The advent of the SARS-CoV-2 pandemic prompted the scientific community to learn the virus dynamics concerning transmissibility, epidemiology, and usefulness of vaccines in fighting emerging health hazards. Pieces of evidence suggest that the first and second doses of mRNA vaccines induce a significant antibody response in vaccinated subjects or patients who recovered from SARS-CoV-2 infection, demonstrating the importance of the previously formed memory. The aim of this work has been to investigate the effects of BNT162b2 Pfizer-BioNTech mRNA-based vaccine booster dose in a cohort of 11 uninfected immunocompetent (ICs), evaluating the humoral and cellular responses, with more carefulness on memory B and T cells. Our findings underscore the potential benefit of the third dose of mRNA vaccine on the lifespan of memory B and T cells, suggesting that booster doses could increase protection against SARS-CoV-2 infection.

B cell tolerance is critical for preventing autoimmunity, yet the mechanisms by which B cells discriminate self from non-self antigens remain incompletely understood. While early findings emphasize the role of classical antigen-mediated BCR signaling strength by varying antigen formats, emerging evidence highlights the importance of mechanical cues during antigen recognition. This review explores how mechanosensitive ion channels, particularly Piezo1, contribute to B cell activation and tolerance by integrating physical forces at the immune synapse.

Avian influenza virus infections pose a potential pandemic threat. The currently licensed vaccines have inherent limitations, emphasizing the urgent need for improved influenza vaccines. Here, we developed a novel hemagglutinin (HA) virus-like particle (VLP) vaccine candidate through the baculovirus expression vector system (BEVS).

Entomopathogenic fungi can precisely inhibit the cellular and humoral immune responses of host insects by secreting effector proteins, allowing them to overcome the innate immune barriers of their hosts. Nodule formation is an immune response primarily mediated by insect hemocytes, which can rapidly and efficiently capture invading pathogenic fungi in the hemocoel. However, the molecular mechanisms by which fungi inhibit insect nodule formation through the secretion of effector proteins remain unclear.

Hematopoiesis is the process responsible for the generation of blood cells in both the circulation and tissues. It plays a crucial role in maintaining homeostasis and defending against infections in animals. Although hematopoiesis is a common feature among animals with a circulatory system, the specific mechanisms involved in hematopoietic events vary significantly among invertebrates.

The innate immune response is a double-edged sword in insects, comprising the humoral and cellular mechanisms to fight and eliminate pathogens. The humoral response is achieved by the production of antimicrobial peptides, which are secreted in the hemolymph. The cellular responses are mediated by phagocytosis, encapsulation and melanization.
