VIH-1 Colo-rectal Transmission by Infected Semen Cells and Effects of Seminal Plasma ex Vivo (CellspermVIH) (CellspermVIH)

March 29, 2023 updated by: University Hospital, Toulouse

VIH-1 Colo-rectal Transmission by Infected Semen Cells and Effects of Seminal Plasma ex Vivo

The objective of our project is to determine the infected seminal cell types and the molecular mechanisms involved in HIV cell-associated transmission in the colo-rectal mucosa, using conditions as close as possible to real life, i.e. seminal leukocytes and seminal plasma from HIV-infected donors and tissue explants

Study Overview

Conditions

Detailed Description

This project relies on:

  • our expertise of HIV in semen and male genital tract and our experience in organotypic cultures;
  • a network of infectious diseases and reproductive biology clinicians to collect, analyze and process seminal cells and seminal plasma from HIV+ donors;
  • the expertise in confocal microscopy and ex vivo colo-rectal model. State of the art culture of colo-rectal tissues, primary cell culture and infection, confocal microscopy, flow cytometry, Polymerase Chain Reaction and Luminex assays for cytokine measurements will be the methodologies primarily used in this project.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

The duplicated part of the CRFs will then be sent to Mrs DEJUC at the IRST in Rennes, the remaining part will be kept in the investigating center.

All the data of the study transcribed by the investigator in the CRFs will be transmitted electronically to the person in charge of the data of the INSERM / IRSET 1085 unit. Upon receipt, the data will be entered simply by typing and re-reading on the Excel spreadsheet. The files will be locked by password and backed up daily with storage for 3 months on the server of the INSERM 1085 unit managed by the IT department of the University of Rennes 1. The set Data is saved every evening, with storage for 4 weeks, then archived monthly on tape.
