Immunotherapy aims to boost a patient’s own immune system to fight disease. In recent years, a variety of immunotherapy strategies aimed at inducing, strengthening or engineering T cell responses have emerged as promising approaches for the treatment of cancer and autoimmune disease.
Here we describe a platform of T cell activation bioassays for the development of CD3 bispecific antibodies and engineered T cell immunotherapies.
Specifically, we developed two bioluminescent reporter-based bioassays to measure T cell activation via CD3 (NFAT-RE) or CD3 + CD28 (IL-2 promoter). These
Cerebral Malaria Insights: Pathogenesis, Host Parasite Interactions including Host ResistancePoster
Cerebral malaria is a dreadful disease transmitted by mosquito. The major preventive approach is focused more in vector control than development of anti-malarial drug. The purpose of this presentation is to analyze different aspects of disease manifestations including clinical symptoms and pathogenesis in the context of mosquito borne infections in different geographical regions of the world.READ MORE
Amoebic Meningoencephalitis: Etiology, Infection and PreventionPoster
The presentation covers the different types of organisms that can cause amoebic meningioencephalitis. The two main types focused on are primary amoebic meningioencephalitis and granulomatous amoebic meningioencephalitis. The method of transmission and target hosts are vastly different. Prevention of these diseases is imperfect at best, as complete avoidance is the only way to not contract the disease.READ MORE
Depressive Symptoms Related to Biological Markers of Immune Functioning among Young People with HIVPoster
Youth living with HIV (YLWH) are at risk for depression. This study aimed to identify trends in depressive symptoms for YLWH in a specialty-care clinic and follow up clinical treatment procedures.READ MORE
