Immune profiling involves characterizing the immune system's response to pathogens, diseases, or other external stimuli. This research area aims to understand the composition, function, and activity of immune cells in the body to better predict and treat various health conditions. Immune profiling can involve analyzing the expression of specific markers or molecules on immune cells, measuring cytokine levels, or assessing immune cell populations using techniques such as flow cytometry or gene expression analysis. This information can help researchers identify correlations between immune responses and disease progression, as well as develop personalized therapies or vaccines based on an individual's immune profile.
