Figure EV1. PyLARC2 immunization elicits long-lived CD8 + T cell-based immunity, especially liver resident CD8 + T cells.

Figure EV1

(A) Experimental schematics for (BE). Nine C57BL/6 mice were immunized three times with 50,000 PyLARC2 sporozoites 1 month apart. Five mock immunized mice received mosquito debris from uninfected salivary glands as a control. Mice were euthanized at 2 months after the last immunization and the livers and spleens were collected for T cell analysis via flow cytometry. (B) (i) frequencies and (ii) the total number of antigen experienced CD8+ memory T cells (CD44hi) in the livers of mock or PyLARC2 immunized mice. (C) (i) frequencies, (ii) total number, and (iii) representative flow layout of CD69hiCXCR6hiliver-resident memory CD8+ T cells (TRM) (gated on CD44hiCD8α+ singlet events). (D) Frequencies and a representative flow layout of CD11ahiCD44hi CD8+ T cells in the liver. (E) (i) frequencies, (ii) total number, and (iii) representative flow layout of CD44hiCD62Llo CD8+ effector memory T cells (TEM) in the spleen. Data is shown as mean ± SD. Statistical analysis was done using non-parametric Mann–Whitney test. P values are indicated in the figure. P > 0.05 is taken as not significant.
