Article Title: Simultaneous Aerosol and Intramuscular Immunization with Influenza Vaccine Induces Powerful Protective Local T Cell and Systemic Antibody Immune Responses in Pigs
doi: 10.4049/jimmunol.2001086
Figure Lengend Snippet: Porcine tissue-resident memory cells. Three pigs from the immunized groups and two control pigs were infused i.v. with CD3 mAb and culled 10 min later. Lymphocytes were isolated and stained ex vivo with the same clone of CD3 Ab labeled with FITC as described in the . As the infused CD3 does not saturate all CD3 sites, some nasal turbinate, tracheal, and lung tissue T cells are double positive (intravascular cells). A proportion of BAL, nasal turbinate, and tracheal cells are unstained by intravascular mAb, indicating tissue residency (top row). The top row shows representative FACS plots for each tissue of infused animal. The bottom row shows staining in animals not infused with CD3 mAb and stained ex vivo. The reported proportion of CD3 ex vivo + CD3 i.v. − and CD3 ex vivo + CD3 i.v. + are calculated from total CD3 + .
Article Snippet: The lymphocytes were then stained with surface markers , including anti-porcine CD3-FITC (clone PPT3; Bio-Rad Laboratories).
