The Role Of Late Antigen In Cd4 Memory T Cell Formation During Influena [I.E. Influenza] Infection: A Dissertation, Bianca L. Bautista 2016 University of Massachusetts Medical School

The Role Of Late Antigen In Cd4 Memory T Cell Formation During Influena [I.E. Influenza] Infection: A Dissertation, Bianca L. Bautista

GSBS Dissertations and Theses

While memory CD4 T cells are critical for effective immunity to pathogens, the mechanisms underlying their generation are poorly defined. Although extensive work has been done to examine the role of antigen (Ag) in shaping memory formation, most studies focus on the requirements during the first few days of the response known as the priming phase. Little is known about whether or not Ag re-encounter by effector T cells (late Ag) alters CD4 memory T cell formation. Since influenza infection produces a large, heterogeneous, protective CD4 memory T cell population, I used this model to examine the role of late ...


Fc Receptor-Mediated Activities Of Env-Specific Monoclonal Antibodies Generated From Human Volunteers Receiving A Dna Prime-Protein Boost Hiv Vaccine: A Dissertation, Matthew R. Costa 2016 University of Massachusetts Medical School

Fc Receptor-Mediated Activities Of Env-Specific Monoclonal Antibodies Generated From Human Volunteers Receiving A Dna Prime-Protein Boost Hiv Vaccine: A Dissertation, Matthew R. Costa

GSBS Dissertations and Theses

Human immunodeficiency type 1 (HIV-1) is able to elicit broadly potent neutralizing antibodies in a very small subset of individuals only after several years’ infection and as a result, vaccines that elicit these types of antibodies have been difficult to design. The RV144 trial showed that a moderate protection is possible, which may correlate with antibody dependent cellular cytotoxicity (ADCC) activity. Previous studies in the Lu lab demonstrated that in an HIV-1 vaccine phase I trial, DP6-001, a polyvalent Env DNA prime-protein boost formulation, could elicit potent and broadly reactive, gp120-specific antibodies with positive neutralization activities along with multiple Fc ...


Human Monoclonal Antibodies To Plasmodium Falciparum Circumsporozoite Protein For Transient Passive Protection Of Malaria Travelers To Endemic Areas, Stuart Nelson, Douglas Golenbock, Ann M. Moormann, Colby A. Souders, Lisa Cavacini 2016 University of Massachusettts Medical School

Human Monoclonal Antibodies To Plasmodium Falciparum Circumsporozoite Protein For Transient Passive Protection Of Malaria Travelers To Endemic Areas, Stuart Nelson, Douglas Golenbock, Ann M. Moormann, Colby A. Souders, Lisa Cavacini

Ann M. Moormann

Plasmodium falciparum, is a protozoa that causes over 214 million cases of Malaria worldwide and the World Health Organization reported an estimated 438,000 deaths attributed to malaria in 2015. Current prevention strategies have reduced malaria cases but they are either costly, have poor efficacy or resistance has begun to develop. There is a global need for an effective pre-exposure prophylaxis treatment.

The leading Malaria vaccine candidate is RTS,S which contains a monovalent Plasmodium falciparum circumsporozoite protein (CSP). The goal of this vaccine is to induce anti-CSP antibodies that would block sporozoite invasion of hepatocytes and thereby hinder parasite ...

Memory Cd8+ T Cell Function During Mycobacterium Tuberculosis Infection: A Dissertation, Stephen M. Carpenter 2016 University of Massachusetts Medical School

Memory Cd8+ T Cell Function During Mycobacterium Tuberculosis Infection: A Dissertation, Stephen M. Carpenter

GSBS Dissertations and Theses

T cell vaccines against Mycobacterium tuberculosis (Mtb) and other pathogens are based on the principle that memory T cells rapidly generate effector responses upon challenge, leading to pathogen clearance. Despite eliciting a robust memory CD8+ T cell response to the immunodominant Mtb antigen TB10.4 (EsxH), we find the increased frequency of TB10.4-specific CD8+ T cells conferred by vaccination to be short-lived after Mtb challenge. To compare memory and naïve CD8+ T cell function during their response to Mtb, we track their expansions using TB10.4-specific retrogenic CD8+ T cells. We find that the primary (naïve) response outnumbers the ...

Background: Despite the length of time HIV has been wreaking havoc on its victims, improvements in the prevention and treatment of HIV are needed. Anti-retroviral therapy can be effective but is expensive and not entirely accessible for people infected in third world countries. Several promising broadly neutralizing antibodies have been isolated from infected individuals; we propose that generating antigen specific human monoclonal antibodies using humanized mice further represents a promising approach to engineer prophylactic antibodies to reduce spread and infection of HIV.

Methods: Immunodeficient mice were engrafted with fetal liver and thymus (BLT) prior to infection with different HIV isolates ...

Despite improving treatment methods and therapeutic options, hepatitis C virus (HCV) remains a major global disease burden, and a vaccine would help greatly in reducing its incidence. Due to its extremely high sequence variability, HCV can readily escape the immune response, thus a vaccine must elicit an immune response toward conserved, functionally important epitopes.

Using structural data of the broadly neutralizing antibody HCV1 in complex with a conserved linear epitope from the HCV E2 protein (aa 412-423, referred to as epitope I or domain E), we performed structure-based design to generate vaccine immunogens to induce antibody responses to this epitope ...

The respiratory bacterial infection caused by Bordetella pertussis (whooping cough) is the only vaccine-preventable disease whose incidence has been increasing over the last 3 decades. To better understand the resurgence of this infection, a baboon animal model of pertussis infection has been developed. Naïve baboons that recover from experimental pertussis infection are resistant both to clinical disease and to airway colonization when re-challenged. In contrast, animals vaccinated with acellular pertussis vaccine and experimentally challenged do not develop disease, but airways remain colonized for 4-6 weeks. We explored the possibility that the IgG antibody response to pertussis infection is qualitatively different ...

Enterotoxigenic Escherichia coli (ETEC) causes significant diarrheal illness in infants in the developing world and travelers to endemic countries including military personnel. Infection of the host involves bacterial colonization of the small intestinal epithelium and toxin secretion leading to watery diarrhea. CFA/I is the most common colonizing factor antigens expressed on the surface of ETEC isolates. The CFA/I adhesin, CfaE, appears to be required for ETEC binding to human intestinal cells for colonization. Human antibodies against the binding domain of CfaE have potential to block colonization of ETEC and serve as a potent immunoprophylactic therapeutic for ETEC-related diarrhea ...

Background. Tick transmission of Borrelia spirochetes to humans results in significant morbidity from Lyme disease worldwide. Serum concentrations of antibodies against outer surface protein A (OspA) were shown to correlate with protection from infection with Borrelia burgdorferi, the primary cause of Lyme disease in the United States.

Methods. Mice transgenic for human immunoglobulin genes were immunized with OspA protein of B. burgdorferi to generate human monoclonal antibodies (HuMabs) against OspA. HuMabs were generated and tested in in vitro borreliacidal assays and animal protection assays.

Results. Nearly 100 unique OspA specific HuMabs were generated and four HuMabs (221-7, 857-2, 319-44, and ...

HIV vaccine efforts tend to focus on the induction of IgG neutralizing antibodies. In part, this may stem from the observations that most HIV infected individuals fail to produce significant mucosal IgA. However, this is unlike most other infections and in turn it can be argued that mucosal IgA with appropriate function and specificity may contribute significantly to the prevention of HIV transmission. To explore this, we previously isotype switched F425A1g8, an anti-HIV CD4i human monoclonal antibody that binds to epitopes exposed upon CD4 binding (CD4i) The VH and VL chains were amplified from the IgG hybridoma and inserted into ...

Through comparative oncogenomic studies and functional analyses, we have identified the bone morphogenetic protein (BMP) factor GDF6 as a new melanoma oncogene. The secreted, carboxy-terminal portion of GDF6 is the active form that binds to cell-surface receptors to initiate BMP signaling. Targeted antibodies directed against secreted proteins are a proven therapeutic modality in several diseases.

To develop therapeutic antibodies against the active form of GDF6, we generated a panel of monoclonal antibodies. Due to the high similarity of human and mouse GDF6 proteins, the C-terminal GDF6 protein was expressed as bacterial recombinant protein with fusion tags to enhance immunogenicity. The ...

Exposure of an Rh negative mother to red blood cells (RBCs) of an Rh positive fetus results in alloimmunization and development of anti-RhD antibodies. The anti-RhD antibodies cause hemolytic disease of the new born babies during subsequent pregnancies. Current prophylactic treatment involves polyclonal anti-RhD IgG purified from plasma of humans and is administered in approximately 20% of pregnancies. While the current prophylaxis is effective, it involves the use of human plasma and non-RhD specific antibodies, thus posing a risk of transmitting infections and undesired antibody reactions. Moreover, there is a serious scarcity of plasma donors to meet the requirement of ...


Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez 2016 Augustana College, Rock Island Illinois

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez

Biology: Student Scholarship & Creative Works

ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 ...

Cryptococcus neoformans is a major opportunistic fungal pathogen that causes fatal meningoencephalitis in immunocompromised individuals and is responsible for a large proportion of AIDS-related deaths. The fungal cell wall is an essential organelle which undergoes constant modification during various stages of growth and is critical for fungal pathogenesis. One critical component of the fungal cell wall is chitin, which in C. neoformans is predominantly deacetylated to chitosan. We previously reported that three chitin deacetylase (CDA) genes have to be deleted to generate a chitosan-deficient C. neoformans strain. This cda1Delta2Delta3Delta strain was avirulent in mice, as it was rapidly cleared from ...
