The microbiome and the immune system are known to work in conjunction to modulate the clearance of pathogens and tolerance of beneficial microbes. A growing area of research seeks to study the potential extent of the involvement of the microbiome in modulating and supporting the immune system during acute allograft rejection. It has been hypothesized that the localized microbiota in each organ produce metabolites that instigate inflammatory immune responses, but whether microbiota interactions precipitate acute allograft rejection is unknown. Therefore, this study focuses on microbiome shifts in the gut and kidney after inducing acute renal transplant rejection in order to implicate gut dysbiosis as a precursor or supporter of allograft rejection. This study also subsequently explores the use of an immune-modulating protein in order to determine differences in the outcome of transplant rejection and potential differences in intestinal microbial load. This experiment sought to induce rejection in BALB/c mice through the use of C57BL/6 mouse renal slivers. Microbiome abundance was analyzed in all experimental groups. Understanding the role of the microbiome in transplant rejection has vast clinical implications and has the potential to enhance pre- and post-operative treatment, and immune management and quality of life following organ transplant.

The microbiome and virome are known to interact within the human body which in turn modulates the health and disease of an individual. While these interactions have been largely studied in bodily sites such as the gastrointestinal tract, the microbiome and virome of the female genital tract (FGT) remains largely understudied. Within the virome exists DNA and RNA viruses which are known to infect both eukaryotes and prokaryotes. While existing virome research within the FGT has focused largely on eukaryote infecting viruses, a large proportion of the virome consists of uncharacterized bacteriophages known as “dark matter”. Due to the lack of a specific gene marker for viruses, which is essential in qPCR quantification of other populations such as bacteria, determination of viral abundance and virome characterization has been limited. However, the staining of viral DNA has been found effective in visualizing and enumerating virus-like particles within various specimens. In this study, we seek to determine viral abundance within the FGT utilizing SYBR Gold nucleic acid stain to visualize VLP present within a cohort of cervicovaginal lavage (CVL) samples. Given these results we intend to draw conclusions regarding the interactions between the FGT virome and viral abundance as well as sexual-reproductive health. Understanding the complex relationship of the virome within the female reproductive tract is likely to have remarkable clinical implications and has the potential to progress both the diagnostic and treatment aspects of female sexual and reproductive health.
