The receptor for interleukin-12, formed by IL-12Rβ1 and IL-12Rβ2, mediates the type I immune responses of various types of lymphocytes. Polymorphisms in IL12RB2, the gene encoding IL-12Rβ2, were reported to be associated with several immune related diseases, such as Crohn's disease. Because the IL23R and IL12RB2 genes are located in close proximity on the genome, the reported associations might also be attributable to linked polymorphisms in IL23R, which were found to be associated with immune related diseases as well. To clarify the role of IL-12Rβ2 in immune diseases, we investigated the functional consequences of thirteen amino acid substitutions in IL-12Rβ2. We developed a model with retroviral expression of IL-12Rβ2 in B cell lines. With the use of this model the expression and function of the variants was compared within the same genetic background. Four of the IL-12Rβ2 variants, N271Y, R313G, A604V and L808R showed reduced IL-12 responses compared to the wild type variant. Two of these are relatively common in some populations and may be used in future association studies to reveal a role for IL-12 in infectious and/or immune related diseases.

Swine acute diarrhoea syndrome coronavirus (SADS-CoV), a novel HKU2-related coronavirus of bat origin, is a newly emerged swine enteropathogenic coronavirus that causes severe diarrhoea in piglets. SADS-CoV has a broad cell tropism with the capability to infect a wide variety of cells from human and diverse animals, which implicates its ability to hold high risks of cross-species transmission. The intracellular antiviral immunity, comprised of the intrinsic and innate immunity, represents the first line of host defence against viral infection prior to the onset of adaptive immunity.

The endophytic fungus Serendipita indica (Si) could suppress Phoma arachidicola (Pa) and control peanut web blotch disease. The study evaluated its growth-promoting and disease-resistant effects in two peanut cultivars, Luhua11 and Baisha1016. In vitro experiments and microscopy analysis demonstrated that S.

Cercosporidium personatum (CP) causes peanut late leaf spot (LLS) disease with 70% yield losses unless controlled by fungicides. CP grows slowly in culture, exhibiting variable phenotypes. To explain those variations, we analyzed the morphology, genomes, transcriptomes and chemical composition of three morphotypes, herein called RED, TAN, and BROWN.

Acute Myeloid Leukemia (AML) with KMT2A rearrangements (KMT2Ar), found on chromosome 11q23, is often called KMT2A-rearranged AML (KMT2Ar-AML). This variant is highly aggressive, characterized by rapid disease progression and poor outcomes. Growing knowledge of epigenetic changes, especially lactylation, has opened new avenues for investigation and management of this subtype.
