Summary: The delayed recovery and reduced numbers of iNKT cells in transplantation conditions are linked to defective generation of thymic iNKT precursors and impaired differentiation of subpopulations under the influence of TCR and co-stimulatory signaling.

Summary: A phosphoserine-loaded chitosan membrane was synthesized to improve the osteogenic effect of chitosan membranes. The incorporation of phosphoserine into chitosan membranes was confirmed and the phosphoserine-chitosan membranes significantly stimulated bone regeneration.

Summary: The dysregulated expression of miR-125b is actively involved in the progression and pathophysiology of acute promyelocytic leukemia. Targeting miR-125b may represent a new therapeutic option for this type of leukemia.

Summary: The number and responsiveness of central and peripheral B cells decrease in aged mice, with significant differences in gene usage in the BCR H-CDR3 repertoire. The diversity of the BCR H-CDR3 repertoire in bone marrow and spleen B cells decreases with age, as seen in the study.

Summary: The study found that aortic macrophage accumulation in abdominal aortic aneurysm (AAA) is primarily caused by adventitial recruitment of Lyve-1(-) macrophages, with a relative depletion of Lyve-1(+) macrophages. Selective targeting of macrophage subtypes may represent a potential novel therapeutic avenue for the medical treatment of AAA.

Summary: This study investigated the effects of molybdenum (Mo) on lymphocyte apoptosis and peripheral blood changes in sheep. The results showed that excessive Mo induced apoptosis-related DNA damage in splenocytes and thymocytes, as well as increased apoptosis indexes of these cells. Excessive Mo treatment also reduced mitochondrial membrane potential (MMP) and promoted apoptosis in peripheral blood lymphocytes. Additionally, the excessive Mo treatment resulted in decreased white blood cell count, lymphocyte count, granulocyte count, and red blood cell count, as well as decreased levels of hemoglobin and hematocrit, and increased red blood cell distribution width.

Summary: Infections after spinal cord injury (SCI) can worsen neurological outcomes and increase mortality. Autonomic dysfunction and impaired neuroendocrine signaling have been identified as key factors in SCI-induced immune deficiency syndrome (SCI-IDS). While mature leukocyte dysfunction is well-known, new data suggests that SCI also affects the development and mobilization of immune cell precursors in bone marrow. This review explores this early manifestation of SCI-IDS as bone marrow failure syndrome.

Summary: Traditional models of lymphopoiesis present B and T cell development as a linear process, but studies have shown that the types of lymphocytes generated before and after birth differ. This review synthesizes data from multiple laboratories, including our own work using mouse models, and demonstrates that innate and conventional B and T cells emerge in different ways and are regulated differently. Understanding this layering of lymphocyte development has implications for the composition of the adult immune system and the origin of lymphocytic leukemias.

Summary: The study aimed to investigate the association of high FDG uptake in the bone marrow and spleen with clinical factors and laboratory values in patients with bacteremia. Results showed that high C-reactive protein levels and a cardiovascular or musculoskeletal focus of infection were positively associated with bone marrow SUV ratios, while age and glucose levels before FDG-PET/CT were negatively associated with bone marrow SUV ratios.

Summary: Transplantation of NPs was found to decrease the expression of inhibitory factors in host neutrophils and reduce proinflammatory cytokines in the lungs after shock, increasing neutrophil migration and enhancing bacterial clearance, indicating the potential of NPs as a cellular therapy for secondary infection following hemorrhagic shock.

Summary: Alcohol consumption affects immune system cell function and increases susceptibility to infections. This study found that chronic alcohol administration alters the metabolomic profile of bone marrow, which may impact immune response.

Summary: Clonal hematopoiesis, a condition where certain hematopoietic stem cell clones generate a disproportionate fraction of blood leukocytes, is correlated with increased risk for cardiovascular disease. Research shows that in individuals with atherosclerosis, hematopoietic stem cell division rates are elevated, leading to an increased risk of clonal hematopoiesis. The study suggests that increased hematopoietic stem cell proliferation is an important factor contributing to the association between cardiovascular disease and clonal hematopoiesis.

Summary: The study aimed to investigate the role of mTOR in the immune response after burn and inhalation injury. The results showed that the murine B+I model had inhalation-specific immune phenotypes and suggested the involvement of mTOR in acute immune dysfunction.
