Summary: HLA-A*11:01 is highly prevalent in East Asian and Oceanian populations and is associated with high risk of severe influenza disease. Using immunopeptidomics, researchers identified novel CD8(+) T cell targets for influenza A and influenza B viruses in HLA-A*11:01-expressing individuals. These findings have implications for the design of broadly cross-reactive influenza vaccines.

Summary: In patients with AAD, a significantly higher frequency of HLA-A2 restricted LLNATIAEV-specific cells was found compared to controls. However, negligible frequencies of EPLARLEL-specific T cells were detected, with significant IFNγ production observed in response to a longer peptide encompassing EPLARLEL. The slightly offset ARLELFVVL peptide was identified as a novel dominant epitope restricted by HLA-C7.

Summary: This study investigated the presence of MHC-I immunodominant viral peptides in coronavirus subfamilies and SARS-CoV-2 Variants of Concern (VOCs) using in silico and in vitro tools. The results showed that HLA-A*02 haplotype had the highest number of immunodominant epitopes but with the lowest combined prediction score. Furthermore, it was observed that the mutations on the VOCs are promoting escape from HLA-A2-mediated antigen presentation, indicating an immune evasion process.

Summary: This study investigates the T-cell receptor specificity and cross-reactivity of two immunodominant wheat gluten epitopes in celiac disease. The researchers find that the differences in binding between the epitopes and T-cell receptors at position 7 explain the cross-reactivity between the two epitopes.

Summary: The HLA-B*27 family of alleles is strongly associated with ankylosing spondylitis (AS), but some non-associated HLA-B*27 variants have been found. The quantity of presented epitopes, rather than the quality, may explain the difference. The ERAP1/2 haplotype and the B*27:05 allele play crucial roles in shaping the CD8+ T cell response to viral and self-B*27 peptides.

Summary: This special edition provides a summary of significant progress in understanding signaling by T lymphocytes. It explores the changes in T cell adhesion and actin cytoskeleton during interactions with antigen-presenting cells (APCs) and other immune cells. The articles discuss the mediators of these changes within T cells and on the T cell surface. They specifically focus on inside-out integrin signaling, components of the immunological synapse, T cell receptor signaling from endosomes, membrane transfer between APCs and T cells via trogocytosis, immune deficiencies in T cell signaling pathways, and the role of THEMIS in thymocyte development and peripheral T cell function.

Summary: Living organisms have evolved in the natural electromagnetic fields of the earth, which include atmospheric electrical circuit, Schumann resonances, and geomagnetic field. The circadian rhythm, which regulates physiological functions, can be affected by both light and the earth's electromagnetic fields. Solar disturbances and weakening of the geomagnetic field can disrupt the circadian rhythm, increase inflammation, and lead to infectious and chronic diseases. Possible mechanisms for sensing the earth's electromagnetic fields involve electron and electromagnetic wave entrainment, light-dependent radical pair formation, and magnetite nanoparticles. Factors such as electromagnetic pollution, shielding materials, and geomagnetic anomalies may also contribute to circadian rhythm disruption and disease development.

Summary: Oral mucosal pathologies are prevalent diseases worldwide and have medical significance. They can cause disfigurement and greatly reduce quality of life in a confined space with important physiological and social functions. However, treatment for these diseases is often ineffective and there is limited research on them. The host's immune system plays a major role in the development, maintenance, and resolution of oral mucosal pathologies, making a precise understanding of immunological mechanisms crucial for accurate diagnosis, targeted immunotherapy, and personalized treatment. This review highlights recent advancements in multiomic and single-cell approaches that provide comprehensive insights and clinically relevant biological signatures for these pathophysiological processes.

Summary: Engineered nanoparticles smaller than 100 nm, such as silica and titanium, are present in various consumer products and can interact with epithelial tissues, leading to inflammation and potential precancerous lesions. Detecting these particles and lesions in biopsies is challenging, especially in clinical settings that screen large numbers of patients. Therefore, there is a need for improved imaging techniques to detect foreign particles and markers of inflammation in epithelial tissues for early disease diagnosis.

Summary: This case report describes a patient with NF1 and vertebral arteriovenous fistulae (AVFs). After endovascular intervention, the AVF disappeared but a new aneurysm appeared during follow-up. Further angiography should be considered in patients with NF1 presenting with neurological symptoms. Awareness of the coexistence between NF1 and AVF or aneurysm is crucial to avoid diagnostic delays.

Summary: The severity and mortality of COVID-19 in patients with diabetes mellitus are often higher, but the reasons for increased susceptibility in these individuals are not fully understood. In this study, the researchers identified a metabolite called 1,5-anhydro-d-glucitol (1,5-AG), which is associated with diabetes and has effective antiviral activity against SARS-CoV-2. They found that the level of 1,5-AG is significantly lower in patients with diabetes, and supplementation of 1,5-AG can reduce viral replication in their serum. In animal experiments, diabetic mice had higher viral loads and more severe respiratory tissue damage when infected with SARS-CoV-2, but sustained supplementation of 1,5-AG reduced the viral loads and disease severity to similar levels as non-diabetic mice. The researchers also discovered that 1,5-AG directly binds to the spike protein of SARS-CoV-2, interrupting the virus-host membrane fusion. These findings suggest that 1,5-AG supplementation may be beneficial for diabetic patients in preventing severe COVID-19.
