Article Abstract
The human major histocompatibility complex (MHC) is a ∼4 Mb genomic segment on Chromosome 6 that plays a pivotal role in the immune response. Despite its importance in various traits and diseases, its complex nature makes it challenging to accurately characterize on a routine basis. We present a novel approach allowing targeted sequencing and de novo haplotypic assembly of the MHC region in heterozygous samples, using long-read sequencing technologies. Our approach is validated using two reference samples, two family trios, and an African-American sample. We achieved excellent coverage (96.6%-99.9% with at least 30× depth) and high accuracy (99.89%-99.99%) for the different haplotypes. This methodology offers a reliable and cost-effective method for sequencing and fully characterizing the MHC without the need for whole-genome sequencing, facilitating broader studies on this important genomic segment and having significant implications in immunology, genetics, and medicine.

Background: γδ T cells possess unique immunological features including tissue tropism, major histocompatibility complex-independent antigen recognition, and hybrid T/natural killer cell properties that make them promising candidates for cancer immunotherapy. However, the therapeutic potential of Vδ1 γδ T cells, particularly when engineered with chimeric antigen receptors (CARs), remains underexplored in solid tumors such as pancreatic cancer (PC), largely due to their low abundance in peripheral blood and challenges in ex vivo expansion. This study aims to directly compare the preclinical safety and efficacy among CAR-engineered Vδ1 γδ T cells, Vδ2 γδ T cells, and conventional αβ T cells.

Except from the myeloid in origin cells, ectopic expression of T-cell receptors (TCRs) was also detected in sperm and the female reproductive tract, which in conjunction with major histocompatibility complex (MHC) molecules suggested their involvement in mate choice. Following-up these observations and considering that MHC/TCR interactions could guide spermatozoa towards ovum, the present study aimed to delineate the presence of TCRs in sperm vis-à-vis cognate recognition and define such expression during spermatogenesis. Immunofluorescence experiments using fertile BALB/c males showed that despite the inbred origin of mice, all combinations of high (HI, >20 % expression) and low (LO, <5 % expression) TCRαβ and TCRγδ expression could be detected in equal distribution rates, followed by an inverse pattern of MHC expression.

Predicting Antibody-Antigen (Ab-Ag) docking and structure-based design represent significant long-term and therapeutically important challenges in computational biology. We present SAGERank, a general, configurable deep learning framework for antibody design using Graph Sample and Aggregate Networks. SAGERank successfully predicted the majority of epitopes in a cancer target dataset.

Small-cell lung cancer (SCLC), an aggressive neuroendocrine tumor strongly associated with exposure to tobacco carcinogens, is characterized by early dissemination and dismal prognosis with a five-year overall survival of less than 7%. High-frequency gain-of-function mutations in oncogenes are rarely reported, and intratumor heterogeneity (ITH) remains to be determined in SCLC. Here, via multiomics analyses of 314 SCLCs, we found that the ASCL1/MKI67 and ASCL1/CRIP2 clusters accounted for 74.

Natural killer (NK) cell licensing is an educational process that enhances responsiveness to activating signals in maturing NK cells and is predominantly regulated by major histocompatibility complex (MHC) class I-specific inhibitory signals. However, the role of non-MHC signalling in this process remains unclear. Here, we investigated the role of FcRγ, an adaptor protein associated with activating receptors, in the regulation of NK cell responsiveness.
