Article Title: The CNS lymphatic system modulates the adaptive neuro-immune response in the perilesional cortex in a mouse model of traumatic brain injury

doi: 10.1101/821645

Figure Lengend Snippet: Pseudocolor dot plots (A) and (B) represent gated subpopulations CD69 vs. CD44 of CD4+ and CD8+, respectively. Stacked bargrams in (C) and (D) show respectively the counts and frequencies of CD8+ T cell subpopulations, as analyzed in the perilesional cortices of WT and TG mice. No significant differences in CD8+ subpopulations were found between genotypes. In CD4+ subpopulation, instead, we observed a significant reduction in the counts of CD44 hi CD69+ and CD44 hi CD69-subpopulations (E) , in K14-VEGFR3-Ig compared to WT mice. However, no differences were observed in the different subpopulation frequencies (F) . Data are presented as mean ± s.e.m. A binomial negative regression was applied to assess statistical differences in the counts of total T cells between WT ipsi and TG ipsi. The Kruskal Wallis test was used for the analysis of frequency distribution. #p < 0.05; *p < 0.05 vs. WT ipsi.

Article Title: A Study of T Cell Tolerance to the Tumor-Associated Antigen MDM2: Cytokines Can Restore Antigen Responsiveness, but Not High Avidity T Cell Function

doi: 10.1371/journal.pone.0000353

Figure Lengend Snippet: (A) Lymph nodes cells from 6–8 week old Ag pos and Ag neg mice were stained with antibodies against CD4, CD8 and Vβ7 and analysed by flow cytometry. Numbers in quadrants are percentage of live-gated lymphocytes. (B) Lymph node cells were stained with antibodies against CD8, Vβ7 and the activation markers CD44, CD62L, CD69 and CD25. Histograms display gated viable CD8 + Vβ7 + cells. Numbers in histograms represent the specific MFI of the activation marker staining for the gated population. Data are representative of at least three independent experiments.

Article Snippet: The following mAbs were used for flow cytometric staining: rat-anti-mouse Vβ7 FITC (Serotec, UK), rat-anti-mouse CD4 FITC, rat-anti-mouse CD8α APC, rat-anti-mouse CD8α Cy-Chrome 5 (CY-5), rat-anti-mouse Vβ7 PE, hamster-anti-mouse CD69 PE, rat-anti-mouse CD25 PE, rat-anti-mouse CD62L-FITC, rat-anti-mouse CD44 PE, rat-anti-mouse CD43 activation-associated glycoform-PE (all BD Biosciences).

Article Title: Role of Lamin A/C on dendritic cell function in antiviral immunity

doi: 10.1101/2024.05.14.593747

Figure Lengend Snippet: Flow cytometry was employed to assess the percentage of activated CD4 T cells, specifically gated on CD25 + or CD69 + cells; Th1-differentiated cells, specifically gated on IFNγ+ cells; and proliferating CellTrace Violet + T cells. Maturation of GM-CSF-derived WT- and LysM-Lmna -/- -BMDCs was undertaken with (A) sonicated VACV extract, (B) Pam3CSK4, or (C) lipopolysaccharide (LPS), and, in all conditions, pulsed with OVA323–339 cognate OT-IIp. (D) WT- or Lmna -/- -BMDCs, matured with LPS and pulsed with the OVA 323–339 cognate OT-II peptide, were s.c. inoculated into CD45.1 OT-II recipient mice. Six days later, pLNs were extracted, and IFNγ-producing CD4 T cells were analyzed by flow cytometry. The data represent means ± SEM and are presented from a representative experiment out of 3 (A and B, n=3) or out of 4 (C, n=4) or out of 2 (D, n=4). Activation data were analyzed using One Way ANOVA and Bonferroni post-test, and proliferation and Th1 differentiation were assessed by unpaired Student’s t-test. Statistical significance was denoted by asterisks (*P < 0.05; **P < 0.01; ***P < 0.001; ns, not significant).
