A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

CD4 T helper cells play a central role in the control of infection by intracellular parasites. How efficiently pathogen-specific CD4 T cells detect infected cells in vivo is unclear. Here, we employed intravital two-photon imaging to examine the behavior of pathogen-specific CD4 T cells at the site of Leishmania major infection. While activated CD4 T cells enter the inflamed tissue irrespective of their antigen specificity, pathogen-specific T cells preferentially decelerated and accumulated in infected regions of the dermis. Antigen recognition by CD4 T cells was heterogeneous, involving both stable and dynamic contacts with infected phagocytes. However, not all infected cells induced arrest or deceleration of pathogen-specific T cells, and dense clusters of infected cells were poorly accessible to migrating T cells. Thus, disparities in the dynamics of T cell contacts with infected cells and local variation in T cell access to infected cells are important elements of the host-pathogen interplay.
