Research Overview & Focus

The researcher's research focuses on the study of systemic immune responses, particularly those involving inflammation, chronic inflammation, and systemic autoimmunity. Their work spans diverse biological pathways, including allergic inflammation, immune response modulation by natural compounds like pleuromycin and hydroethanol, and systemic inflammation mechanisms such as Allergic asthma and inflammatory bowel disease. The researcher's studies utilize a combination of pharmacological agents, synthetic extracts, and functional biopsies to investigate the role of natural molecules in modulating systemic inflammation and their potential therapeutic applications.
