Decoding the human immune system to predict health, disease, and therapeutic response

By studying the immune system as an integrated system, JAX researchers are uncovering the mechanisms that drive immune health and disease — advancing precision approaches for cancer, infectious diseases, autoimmune disorders, and healthy aging.

The immune system influences nearly every aspect of human health, from resistance to infection and cancer to healthy aging and tissue repair. Yet immune responses vary dramatically from person to person, shaped by genetics, environment, diet, metabolism, age, and prior immune experience.

At JAX, researchers are developing a systems-level understanding of immunity by integrating immunology with genomics, computational biology, and advanced mouse and cellular models. JAX scientists investigate the molecular and cellular mechanisms that shape immune resilience and dysfunction, enabling discovery of biomarkers, therapeutic targets, and precision medicine strategies for cancer, infectious diseases, autoimmune disorders, and age-related immune decline.

Systems immunology research at JAX 

JAX researchers combine immunology, single-cell genomics, and computational modeling to understand how immune systems vary across individuals and how those differences influence health and disease outcomes.

Our work spans:

  • Immune aging and longevity — defining how immune systems change across the lifespan and identifying mechanisms that promote healthy aging.
  • Cancer immunotherapy — uncovering cellular programs that determine anti-tumor immune responses and developing strategies to improve immunotherapies.
  • Infectious diseases and vaccines — understanding why individuals respond differently to pathogens and vaccination.
  • Immunometabolism — revealing how metabolic pathways regulate immune cell function and disease susceptibility.
  • Immunogenomics and systems biology — leveraging multi-omics, machine learning, and advanced computational approaches to decode immune complexity.
  • Immune monitoring and precision immunology — developing biomarkers and predictive tools to guide personalized treatment and prevention strategies.
  • Sex and immune dimorphism — decoding how biological sex shapes immune systems in health and disease.
  • Neuroinflammation — investigating how the immune system drives neurological disease and pain sensitization.
  • Humanized mouse models — creating tools that allow tissue engraftment and translational studies of human disease.
  • Host-microbiome interactions — bioengineering tools to understand host-microbe mutualism in inflammatory and autoimmune conditions.

"JAX is uniquely positioned to lead the field of systems immunology. By integrating biological discovery with data science, JAX researchers are building a predictive understanding of the immune system that will transform the prevention, diagnosis, and treatment of disease."

Science in action

Skin is our most accessible organ. Could it reveal new clues about aging and frailty?

When it comes to aging skin, scientists think of much more than wrinkles. They think of an organ with multitudes of microbes, immune cells, structural proteins, and chemical signals that constantly interact with one another. JAX’s Sasan Jalili is investigating how to probe the complex biological interactions in skin to gain a better understanding of the physiological decline that comes with aging apart from the number of birthdays someone has had—and to reveal new insights about possible interventions to promote healthy aging. Jalili argues that skin is an accessible ecosystem that scientists may be able to sample repeatedly and relatively easily for clues into the biology of aging.
