(C) Overall % of Th1 (CXCR3+) and Th2+Th17 (CXCR3-) within cTFH of HC (n = 11), ESRD-Stable (n = 26), and ESRD-DSA+ (n = 8). each time point from individuals are demonstrated as imply SEM. Results from DSA+ individuals are demonstrated as black packed squares, whereas from stable individuals as black packed triangles. (A) Percentage of Ki67 manifestation on cTFH (remaining panel) and on total CD4+ T cells (ideal panel). Thymoglobulin-induced KTx individuals (Stable n = 7, DSA+ n = 9) and Basiliximab-induced KTx individuals (Stable n = 11, DSA+ n = 3). (B) cTFH cell memory space distribution is displayed as the percentage of CM (CD45RO+CD62L+, left panel) and EM (CD45RO+CD62L-, right panel) from your Thymoglobulin group (DSA+ n Carisoprodol = 8, Stable n = 14). For some of the individuals in Panels A and B some data points are missing. ? 0.05. mmc2.docx (162K) GUID:?BCFC96AC-4AEA-404D-A245-7C818993CF56 Number?S3 KTx recipients that developed DSA post-Tx display elevated PD-1hiCXCR3+-cTFH cells. Cross-sectional phenotypic analyses were performed within the 1st blood sample acquired after DSA detection in the serum. Related time points were selected for stable individuals for assessment. Gating strategy to determine the percentage of PD-1hiCXCR3+ on cTFH and overall data (HC: n = 7; Thymoglobulin group: Stable n = 8, and DSA+ n = 6; Basiliximab group: Stable n = 5, and DSA+ n = 2). Each dot represents 1 subject, and the horizontal lines are of the mean ideals. HC are displayed by packed circles, Thymoglobulin-induced individuals by packed squares, and Basiliximab-induced individuals by open squares. Two-tail College student test or Mann-Whitney test were used relating to data distribution. ? 0.05. mmc3.docx (147K) GUID:?C778CB06-82B3-4DD9-B88E-700AAbdominal85263E Number?S4 Elevated PD1hiTh1-cTFH with EM phenotype results were confirmed in an independent cohort of thymoglobulin-induced KTx individuals from UPMC. Cross-sectional phenotypic analyses were performed within the 1st blood sample acquired after DSA detection in the serum. Related time points were selected for stable individuals for assessment.
