Article Title: Electrical stimulation improved cognitive deficits associated with traumatic brain injury in rats

doi: 10.1002/brb3.667

Figure Lengend Snippet: Flow cytometry detection of endothelial progenitor cells ( EPC s) in peripheral blood of rats before the traumatic brain injury ( TBI ) (0 day), and 1, 3, 7, 14, 21, 28 days after TBI . They were marked by CD 34 and CD 133. The stress of TBI mobilized the EPC s at 1 day after TBI in N‐ ES group and ES group. Electrical stimulation treatment increased EPC s numbers in peripheral blood from 3 to 21 days after TBI . n = 6/group; * p < .05 ES group versus N‐ ES group; # p < .05 N‐ ES group and ES group versus Sham group

Article Snippet: CD34 + cells in brain tissue were detected using a CD34 antibody (R and D Systems Cat# AF4117 Lot# RRID:AB_2074613 ) as recommended by the manufacturer.

doi: 10.1101/2021.03.11.434711

Figure Lengend Snippet: Propranolol combined with anti CTLA4 increases the number of intratumoral CD8+ T cells, reduces tumor angiogenesis, and provides long lasting immune memory against MCA205 cancer cells. A and C , Representative CD8 ( A ) and CD34 ( C ) IHC staining of MCA205 tumor tissues; hematoxylin counterstain; scale bar 100µm (left panels), and 50µm (right panels). B and D , Dot plot showing quantification of CD8 ( B ), and CD34 staining ( D ). Splenocytes from cured mice were re-stimulated ex vivo with MCA205 cancer cells for 24 hours, and intracellular cytokine expressions were quantified by flow cytometry. E , Representative flow cytometry dot plots showing the expression of TNFα and IFNγ on CD4+ T cells (upper panels) or CD8+ T cells (lower panels) with memory phenotype from naïve mice (left panels) or anti-CTLA4+PRO treated mice that had shown complete tumor regression(right panels). F , Percentages of tumor reactive T cells (IFNy+ or TNFa+) with memory phenotype (CD44hi) among CD8+ or CD4+ T cells after 24-hour ex vivo re-stimulation. *p<0.05 according to multiple t test with Bonferroni correction. Mean ± SEM are depicted.
