Lymphocytes play a critical role in adaptive immunity and defense mechanisms, but the molecular mechanisms by which hematopoietic stem and progenitor cells differentiate into T and B lymphocytes are not fully established. Pioneer studies identify several transcription factors essential for lymphoid lineage determination. Yet, many questions remain unanswered about how these transcription factors interact with each other and with chromatin at different developmental stages. This interaction regulates a network of genes and proteins, promoting lymphoid lineage differentiation while suppressing other lineages. Throughout this intricate biological process, any genetic or epigenetic interruptions can derail normal differentiation trajectories, potentially leading to various human pathologic conditions. Here, we summarize recent advances in understanding lymphoid cell development, which was the focus of the Winter 2024 International Society for Experimental Hematology webinar.

Background: T/histiocyte-rich large B-cell lymphoma (T/HRBCL) is a highly aggressive subtype of diffuse large B-cell lymphoma characterized histologically by the presence of a few neoplastic large B cells amidst an abundant background of reactive T lymphocytes and/or histiocytes. T/HRBCL commonly affects the lymph nodes, followed by extranodal sites, such as the spleen, liver, and bone marrow, with rare occurrences in the gastrointestinal tract. Primary gastrointestinal T/HRBCL lacks specific clinical and endoscopic manifestations, and it is difficult to differentiate from inflammatory diseases, nodular lymphocyte predominant Hodgkin lymphoma, and other diseases on a histological basis, thereby hindering early diagnosis.

Tumor immunotherapy has achieved breakthroughs in a variety of tumors. However, the systemic absence of T cells in tumors and immunosuppressive tumor microenvironment so far limits the efficacy of immunotherapy to a small population of patients. Therefore, novel agents to increase T-cell tumor infiltration are urgently needed in the clinic.

Background: Epidemiological investigations have revealed a significant association between alcohol consumption and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Nevertheless, the potential mechanisms are still inadequately revealed. This research aimed to investigate the impact of alcohol on CP/CPPS using an animal model and to elucidate the underlying mechanisms.

Background: Fibrotic skin disease represents a major global healthcare burden, characterized by fibroblast hyperproliferation and excessive accumulation of extracellular matrix components. The immune cells are postulated to exert a pivotal role in the development of fibrotic skin disease. Single-cell RNA sequencing has been used to explore the composition and functionality of immune cells present in fibrotic skin diseases.

Background: Patients with pancreatic ductal adenocarcinoma (PDAC) face a highly unfavorable outcome and have a poor response to standard treatments. Immunotherapy, especially therapy based on natural killer (NK) cells, presents a promising avenue for the treatment of PDAC.
Aims: This research endeavor seeks to formulate a predictive tool specifically designed for PDAC based on NK cell-related long non-coding RNA (lncRNA), revealing new molecular subtypes of PDAC to promote personalized and precision treatment.
