Reassessing The Transcriptional Regulation Of Protective Cd4 T Cell Responses Against Influenza A Virus, Kunal Dhume Jan 2021

Reassessing The Transcriptional Regulation Of Protective Cd4 T Cell Responses Against Influenza A Virus, Kunal Dhume

Electronic Theses and Dissertations, 2020-2023

An attractive strategy to improve efficacy of current Influenza A Virus (IAV) vaccines is to promote protective CD4 T cell responses. Antiviral CD4 T cell responses are predominantly classified as strong IFN-gamma producing T helper type 1 (Th1) cells. Yet, the role of IFN-gamma in protection against IAV is still unclear, suggesting absolute Th1 polarization may be expendable for effective IAV immunity. Here we test this hypothesis using models that restrict the deficiency of known transcriptional regulators of Th1 immunity in only CD4 T cells, avoiding indirect impact on other immune cell responses. We find the 'master regulator' of Th1 …

Moderate Heat-Assisted Gene Electrotransfer For Cutaneous Delivery Of A Dna Vaccine Against Hepatitis B Virus, Chelsea Edelblute, Cathryn Mangiamele, Richard Heller

Bioelectrics Publications

An estimated 350 million people are living with chronic Hepatitis B virus (HBV) worldwide. Preventative HBV vaccination in infants has reduced the disease burden; however, insufficient immunization programs and access obstacles leave vulnerable populations at risk for infection in endemic regions. Gene electrotransfer (GET) using a noninvasive multielectrode array (MEA) provides an alternative platform for DNA vaccination in the skin. DNA vaccines are nonlive and nonreplicating and temperature stable unlike their counterparts. In addition, their simple engineering allows them to be manufactured quickly at a low cost. In the current work, we present the combination of GET and moderate heating …

Nasser, Surinder K. Batra, Govindan Rangarajan, Erminia Massarelli, Herbert Levine, Mohit Kumar Jolly, Prakash Kulkarni, Ravi Salgia

Journal Articles: Biochemistry & Molecular Biology

Drug resistance, a major challenge in cancer therapy, is typically attributed to mutations and genetic heterogeneity. Emerging evidence suggests that dynamic cellular interactions and group behavior also contribute to drug resistance. However, the underlying mechanisms remain poorly understood. Here, we present a new mathematical approach with game theoretical underpinnings that we developed to model real-time growth data of non-small cell lung cancer (NSCLC) cells and discern patterns in response to treatment with cisplatin. We show that the cisplatin-sensitive and cisplatin-tolerant NSCLC cells, when co-cultured in the absence or presence of the drug, display dynamic group behavior strategies. Tolerant cells exhibit …

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Food insecurity is a global problem that requires a One Health approach. As many households in low- and middle-income nations rely on crops and livestock that they produce to meet their household’s needs, food security and nutrition are closely linked to the health of animals and the environment. Resources controlled by women are more often allocated to uses that benefit the entire household, such as food, health, and educating children, than men’s resources. However, studies of gender control of resources among pastoralist societies are scant. We examined the effect of female and male control of livestock resources on food …
