Area of Science:

  • Immunology
  • Biotechnology
  • Vaccinology

Background:

  • Dendritic cells are key antigen-presenting cells that initiate T cell responses.
  • Their capacity to stimulate immunity is crucial for developing vaccines against cancer and infectious diseases.
  • Current challenges lie in optimizing dendritic cell-based vaccine protocols for clinical application.

Purpose of the Study:

  • To review strategies for genetic modification of dendritic cells.
  • To enhance the effector functions of dendritic cells for immunotherapy.
  • To explore gene transfer methods and candidate genes for dendritic cell-based vaccines.

Main Methods:

  • Review of viral and non-viral gene transfer techniques into dendritic cells.
  • Analysis of genes encoding antigens, co-stimulatory molecules, cytokines, and chemokines for transfer.
