The use of invertebrates for in vivo studies in microbiology is well established in the scientific community. Larvae of are a widely used model for studying pathogenesis, the efficacy of new antimicrobial compounds, and immune responses. The immune system of larvae is structurally and functionally similar to the innate immune response of mammals, which makes this model suitable for such studies. In this review, cellular responses (hemocytes activity: phagocytosis, nodulation, and encapsulation) and humoral responses (reactions or soluble molecules released in the hemolymph as antimicrobial peptides, melanization, clotting, free radical production, and primary immunization) are discussed, highlighting the use of as a model of immune response to different human pathogenic microorganisms.

B-lymphocytes play major adaptive immune roles, producing antibody and driving T-cell responses. However, how immunometabolism networks support B-cell activation and differentiation in response to distinct receptor stimuli remains incompletely understood. To gain insights, we systematically investigated acute primary human B-cell transcriptional, translational and metabolomic responses to B-cell receptor (BCR), Toll-like receptor 9 (TLR9), CD40-ligand (CD40L), interleukin-4 (IL4) or combinations thereof.

MS4A4A belongs to the MS4A tetraspan protein superfamily and is selectively expressed by the monocyte-macrophage lineage. In this study, we aimed to evaluate the role of MS4A4A+ macrophages in rheumatoid arthritis (RA) pathogenesis and response to treatment. RNA sequencing and immunohistochemistry of synovial samples from either early treatment-naïve or active chronic RA patients showed that MS4A4A expression positively correlated with synovial inflammation.

Lymphotoxin β receptor (LTβR/TNFRSF3) signaling plays a crucial role in immune defense. Notably, LTβR-deficient (LTβR) mice exhibit severe defects in innate and adaptive immunity against various pathogens and succumb to infection. Here, we investigated the bone marrow (BM) and peritoneal cavity (PerC) compartments of LTβR mice during infection, demonstrating perturbed B-cell and T-cell subpopulations in the absence of LTβR signaling.

Cell death mechanisms play a fundamental role in mycobacterial pathogenesis. We critically reviewed 94 research manuscripts, 44 review articles, and 4 book chapters to analyze important discoveries, background literature, and potential shortcomings in the field. The focus of this review is the pathogen (Mtb) and other Mtb and complex microorganisms.

Contagious bovine pleuropneumonia (CBPP), caused by subsp. (Mmm), is a devastating cattle disease with high morbidity and mortality, threatening cattle productivity in Sub-Saharan Africa and potentially in parts of Asia. Cross-border livestock trade increases the risk of CBPP introduction or reintroduction.
