Application

The CMV Enzyme-Linked ImmunoSpot (ELISpot) Human Kit is a highly sensitive method used to detect and quantify individual cells that secrete IFN-γ, IL-2, and TNF-α after stimulation with the ImmuneSelect CMV Peptide Pool. This assay is utilized in immunology to monitor cellular immune responses at the single-cell level and reliably detects and measures cytokine secretion by stimulated effector cells.

Description

Human Cytomegalovirus (CMV) is a prevalent herpesvirus that infects most people worldwide. While CMV infection is often asymptomatic in healthy individuals, it poses significant health risks to immunocompromised patients, such as those undergoing organ transplantation, and to infants born to infected mothers. CMV infection is a significant cause of morbidity and mortality in these populations, leading to complications like pneumonia, retinitis, gastrointestinal disease, and encephalitis.

Assessment of CMV-specific cellular immunity is vital for controlling viral replication and preventing disease, particularly for recipients of donor transplants. ELISpot assays can be utilized to measure CMV-specific T-cell responses by detecting cytokine production in response to viral peptides derived from CMV antigen. These assays can help identify individuals at higher risk of CMV disease by assessing their cellular immune response, thereby guiding antiviral prophylaxis and treatment strategies. Research has demonstrated that robust CMV-specific T-cell responses correlate with lower rates of CMV disease post-transplantation, underscoring the importance of immune monitoring in managing CMV infections.
