Immunoregulation Section

Arya Biragyn, Ph.D., Chief

The focus of Dr. Biragyn’s research is to understand the “immunological paradox of aging”; that is, why cancer incidence is enhanced but cancers often grow more slowly in older people, and why autoimmunity is more prevalent in the elderly but older people have poor vaccine responses. He hypothesizes that this may be a reflection of disbalance between the regulatory immune system and the accumulation of potentially pathogenic immune cells in aging. His goal is to gain insights in aging immune dysregulation and cancer immunoregulation to develop a simple but potent immunotherapeutics tailored for elderly.

Portfolio/Research Areas

  • Regulatory Immune cells in cancer escape
  • Aging immune dysregulation
  • Development of immunotherapeutic strategies
