Transmission of cytomegalovirus (CMV) to CMV negative transplant or blood recipients should be avoided in organ transplantations, since CMV infection of immunocompromised patients can result in severe illness. The infectivity of organ and blood donors is judged on the basis of CMV antibody, considering CMV IgG positives as potentially infectious. Several sensitive test systems are available for testing organ and blood donors for CMV IgG antibody which should be carried out prior to each transplantation. A series of sera were tested comparatively for CMV IgG antibody by latex agglutination test, ELISA and immunofluorescence. It was found that the rapid and easily performed latex agglutination test was much less sensitive than were the other techniques employed. As a consequence, positive latex agglutination test results are acceptable, only, while negative results should be controlled by more sensitive methods.

Cytomegalovirus infections and reactivations are more frequent in people living with HIV (PLWH) and have been associated with increased risk of HIV progression and immunosenescence. We explored the impact of combination antiretroviral therapy (cART) on latent CMV infection in 225 young adults parenterally infected with HIV during childhood. Anti-CMV IgG antibodies were present in 93.

Idecabtagene vicleucel (ide-cel), an anti-B-cell maturation chimeric antigen receptor T-cell therapy, represents an unprecedented treatment option for relapsed/refractory multiple myeloma (R/R MM). Nevertheless, given its limitations, including the risk of adverse effects and unclear durability of efficacy, there remains a need to report the real-world clinical outcomes of ide-cel therapy in patients with R/R MM, as well as explore host predictive factors for therapy. We performed a single-center retrospective analysis of 25 adult patients with R/R MM who received ide-cel between 2021 and 2023 at the University of California San Diego Health.

Problem: Natural killer (NK) cells undergo education for full functionality via interactions between killer immunoglobulin-like receptors (KIRs) or NKG2A and human leukocyte antigen (HLA) ligands. Presumably, education is important during early pregnancy as insufficient education has been associated with impaired vascular remodeling and restricted fetal growth in mice. NK cell education is influenced by receptor co-expression patterns, human cytomegalovirus (CMV), the HLA-E107 dimorphism, and HLA-B leader peptide variants.

Introduction: The envelope proteins syncytin-1 and pHERV-W from the Human Endogenous Retroviral family 'W' (HERV-W) have been identified as potential risk factors in multiple sclerosis (MS). This study aims to evaluate both humoral and cell-mediated immune response to antigenic peptides derived from these proteins across different clinical forms and inflammatory phases of MS.
Methods: Indirect enzyme-linked immunosorbent assay (ELISA) was employed to measure immunoglobulin G (IgG) responses to syncytin-1 and pHERV-W peptides in MS patients.

Dimeric IgA (dIgA) is the dominant antibody in many mucosal tissues. It is actively transported onto mucosal surfaces as secretory IgA (sIgA) which plays an integral role in protection against enteric pathogens, particularly in young children. Therapeutic strategies that deliver engineered, potently neutralizing antibodies directly into the infant intestine through breast milk could provide enhanced antimicrobial protection for neonates.
