Immune profiling refers to the comprehensive analysis of an individual's immune system to understand its functionality, responsiveness, and diversity. This process involves assessing various immune cells, proteins, and molecules present in the body, providing insights into how the immune system responds to infections, diseases, or therapeutic interventions. Techniques such as flow cytometry, genomics, proteomics, and bioinformatics are utilized to characterize immune cells' behavior and their interactions within the body. Immune profiling plays a crucial role in personalized medicine, aiding in the development of targeted therapies, vaccines, and treatments tailored to an individual's specific immune profile. By decoding the complexities of the immune system, immune profiling contributes to advancing diagnostics, disease monitoring, and the discovery of novel therapeutic strategies.
