The mechanism of spermatozoa-lymphocyte interaction was studied using spermatozoa and lymphocytes obtained from 11 healthy individuals and from 2 patients with spermatocoele. The lymphocytes activated by spermatozoa in 3-day cultures were used as inducers of fresh, unstimulated autologous or allogeneic lymphocytes. In 9 cases of 13 tested sperm samples, a slight proliferative response of lymphocytes stimulated by spermatozoa-induced lymphocytes was observed. The final effect did not depend on whether an autologous or an allogeneic system was used in the first and the second incubation. A possible explanation of the observed reaction is discussed.

Background: Even though major improvements have been made in the treatment of myeloma, the majority of patients eventually relapse or progress. Patients with multiple myeloma who relapse after initial high-dose chemotherapy with autologous stem cells have a median progression free survival up to 2-3 years, depending on risk factors such as previous remission duration. In recent years, growing evidence has suggested that allogeneic stem cell transplantation could be a promising treatment option for patients with relapsed or progressed multiple myeloma.

The December 2024 US Food and Drug Administration (FDA) approval of Mesoblast's Ryoncil (remestemcel-L-rknd)-allogeneic bone marrow mesenchymal stromal cell (MSC(M)) therapy-in pediatric acute steroid-refractory graft-versus-host-disease finally ended a long-lasting drought on approved MSC clinical products in the United States. While other jurisdictions-including Europe, Japan, India, and South Korea-have marketed autologous or allogeneic MSC products, the United States has lagged in its approval. The sponsor's significant efforts and investments, working closely with the FDA addressing concerns regarding clinical efficacy and consistent MSC potency through an iterative process that spanned several years, was rewarded with this landmark approval.

Autologous or allogeneic platelet-derived extracellular vesicles (pEVs) show potential in enhancing tissue recovery and healing chronic wounds. pEVs promote neovascularization and cell migration while reducing inflammation, oxidative stress, and scarring. However, their efficacy in clinical settings is challenged by their susceptibility to washout by wound exudate.

Background: The benefit of universal CAR-T cells over autologous CAR-T cell therapy is that they are a treatment that is ready to use. However, the prevention of graft-versus-host disease (GVHD) and host-versus-graft reaction (HVGR) remains challenging. Deleting class I of human leukocyte antigen (HLA-I) and class II of human leukocyte antigen (HLA-II) can prevent rejection by allogeneic T cells; however, natural killer (NK) cell rejection due to the loss of self-recognition remains unresolved.

Objective: Diabetes is a potential late consequence of childhood and young adult cancer (CYAC) treatment. Causative treatments associated with diabetes have been identified in retrospective cohort studies but have not been validated in population-based cohorts. Our aim was to define the extent of diabetes risk and explore contributory factors for its development in survivors of CYAC in the United Kingdom.
