In addition, infiltration of immune cells and inflammation between lung and diaphragm, close to the thoracic cavity (TC), the site of infection, was only slightly reduced especially around lung tissue upon adoptive transfer of naïve CD4+ T cells (Figure 1F), suggesting that naïve CD4+ or CD8+ T cell transfer is not sufficient to significantly reduce worm burden and inflammation in the TC. Here, CD8A is linked to infection.
