Cellular quantification at day three post-stroke did not reveal changes in absolute counts (Figure 4A, bar graph – left two columns) or percentages (Figure 4A, bar graph – right two columns) of CD4 T-cells in either the draining lymph node of the brain (cervical lymph node, Figure 4A) or the peripheral immune system (spleen, Figure 5A). Here, CD4 is linked to stroke disorder.
