Exosomes In Transmission And Blocking Of Arthropod-Borne Flaviviral Infection And Pathogenesis, Wenshuo Zhou Apr 2020

Exosomes In Transmission And Blocking Of Arthropod-Borne Flaviviral Infection And Pathogenesis, Wenshuo Zhou

Biomedical Sciences Theses & Dissertations

Vector-borne diseases (VBDs) are human illnesses that are transmitted by vectors such as ticks, mosquitoes, and fleas. These arthropods transmit infectious pathogens such as viruses, protozoa, and bacteria, to humans during their blood-feeding. According to the estimation of the WHO, billions of people are affected by VBDs worldwide, and about 700,000 deaths are reported annually. Currently, very few reliable VBDs control approaches and vaccines available to treat various VBDs. Additionally, approaches to control arthropod’ proliferation and migration are difficult to develop. Furthermore, molecular determinants and mechanisms for the transmission are poorly understood. This work describes two studies identifying the novel …


Molecular Candidates For Blocking The Transmission Of Vector-Borne Diseases, Ashish Naresh Vora Jan 2018

Molecular Candidates For Blocking The Transmission Of Vector-Borne Diseases, Ashish Naresh Vora

Biological Sciences Theses & Dissertations

Vector-borne diseases (VBDs) require urgent attention as they have a high mortality rate, with 700,000 people dying in a year as of 2017. So far, extremely few reliable vaccination strategies and solutions have emerged. Transmission blocking vaccines are one among many solutions available to manage the control of VBDs. These require identification of both vector and pathogen molecules that play important roles in the transmission, dissemination and establishment of VBDs. Our strategy is to characterize these candidates that play important roles in vector-host-pathogen interactions. This manuscript presents two such studies identifying the participation of two arthropod molecules in vector-host-pathogen interactions. …
