A career history of fundamental discovery and translational research in immunology has guided Dr. Ware to identify new drug targets and develop novel therapeutics. Dr. Ware’s career in immunology and virology began in 1982 when he became a Professor at the University of California, Riverside’s Division of Biomedical Sciences. In 1996, he joined the La Jolla Institute for Immunology in San Diego as Head of the Division of Molecular Immunology. Professor Ware joined Sanford Burnham Prebys Medical Discovery Institute in 2010, serving as the Director of the Infectious and Inflammatory Disease Center and Adjunct Professor of Biology at the University of California at San Diego. He is currently the Director of the Laboratory of Molecular Immunology, which focuses on discovering and designing immunotherapeutics.
As an educator, he taught medical students immunology and virology. He trained over 60 postdoctoral fellows and graduate students who chose careers in research in academic and pharmaceutical science, patent law, or teaching.
Dr. Ware advises scientific panels and review boards for the National Institutes of Health and serves on the scientific advisor boards for the Allen Institute for Immunology and the Arthritis National Research Foundation. Scientific advisor with several biotechnology and pharmaceutical companies on immunotherapy for cancer and autoimmune diseases using innovative approaches to target discovery and drug development.
Dr. Ware’s research program is dedicated to unraveling the intricate intercellular communication pathways that govern immune responses. His work, which centers on cytokines in the Tumor Necrosis Factor (TNF) Superfamily, particularly those that regulate cell survival and death in response to viral pathogens, spans the domains of cancer,autoimmune and infectious diseases.
At Sanford Burnham Prebys, Dr. Ware is pivotal in promoting the translation of the faculty’s scientific discoveries. His efforts have led to the Institute’s reputation as a productive and preferred partner in collaborations with Pharma, including multi-year research and drug development projects with Eli Lilly and Avalo Therapeutics. His success translating fundamental knowledge into rational drug design has led to three novel therapeutics targeting inflammatory pathways, currently in clinical trials.

Research in the Laboratory of Molecular Immunology is directed at defining the intercellular communication pathways controlling immune responses. Our work is focused on the Tumor Necrosis Factor (TNF)-related cytokines in regulating decisions of cell survival and death, especially in responses to viral pathogens. Translational research is redirecting the communication networks of TNF superfamily to alter the course of autoimmune and infectious disease and cancer.
Carl Ware’s Research Report
Discovery of the TNF-LIGHT-LTαβ Network
The molecular elements of this cellular communication network were revealed with our discovery of Lymphotoxin-β and its formation of the trimeric heterocomplex with LTαβ1 and its signaling receptor, Lymphotoxin-β Receptor2. The LTβR revealed a new inter-cellular communication pathway that provides a key mechanism underlying the development and homeostasis of lymphoid organs. A second ligand we discovered, LIGHT (TNFSF14), is a novel ligand for the herpesvirus entry mediator (HVEM; TNFRSF14), and surprisingly, the LTβR3 heralding the concept that TNF, LTαβ, and LIGHT form an integrated signaling network thru distinct receptors controlling inflammation and host defense.4
LTβR Signaling in Host Defense and Immune Evasion
Our investigations into the mechanisms of virus evasion of the immune system revealed an essential role of the LTβR pathway in regulating the type 1 interferon response to cytomegalovirus5 and now recognized as a major defense against other pathogens. LTβR signals differentiate macrophages and stromal cells into IFN-producing cells. LTβR transcriptomics and proteomics datasets we generated revealed a novel constellation of anti-viral host defense mechanisms6. Importantly the role of the LTβR pathway to alter tissue microenvironments by differentiation of specialized stromal cells has implications for promoting effective immune responses to cancer.
Discovery of the HVEM-BTLA Immune Checkpoint
The discovery that HVEM is a coreceptor for the immune checkpoint, B and T lymphocyte attenuator (BTLA), an Ig superfamily member, established a new paradigm in TNF Receptor signaling pathways 7. Additional investigations revealed the importance of the HVEM-BTLA system in limiting immune responses, including T cell help for B cell clonal expansion, antibody maturation, and secretion8. HVEM-BTLA also regulates control of the intestinal microbiome, limiting invasion of pathogenic bacteria and enhancing Treg cell homeostasis 9. The diverse roles of this pathway are seen in the loss of BTLA signaling from mutations in HVEM frequently present in B cell lymphomas10. Additional layers of immune regulators, CD160 and DcR3, control the LIGHT-HVEM-BTLA pathways, revealing this network as a key mechanism controlling immune homeostasis.
Appreciating the fundamental features of the TNF-LIGHT-LTab Network in effector and homeostasis mechanisms presents a target-rich resource for therapeutic intervention in autoimmunity, infection, and cancer11, 12.
Translational research and Immunotherapy
2021-current: Lead Scientific Advisor, Avalo Therapeutics A neutralizing, fully human mAb (quisovalimab) to the proinflammatory cytokine LIGHT (TNFSF14) completed Phase I with an excellent safety profile and a Phase II trial establishing efficacy in COVID-19 pneumonia (NCT0441205)13. We identified elevated serum levels of LIGHT in hospitalized patients with COVID1914 spurring a randomized, double-blind, multicenter, proof-of-concept trial with adults hospitalized with COVID-19-associated pneumonia and mild to moderate ARDS15. The results established efficacy with a significant proportion of patients remaining alive and free of respiratory failure through day 28 after receiving quisovalimab, most pronounced in patients >60 years of age (76.5% vs. 47.1%, respectively; P = 0.042). These results and animal models validated LIGHT as a target for non-COVID inflammatory conditions, clinical trials ongoing in asthma (NCT05288504)12.
