Figure Lengend Snippet: Figure 2. IL-32 induces CD14D APC that support malignant T-cell survival. (a) Survival of purified T cells versus PBMC from a patient with stage IV CTCL after culture with IL-32 and submitogenic IL-2. (b) IL-32b supported the survival of malignant and benign T cells and CD14þ myeloid cells. Five additional donors showed similar results. (c, d) HTS confirmed the persistence of malignant T cell TCRs in culture. (e) IL-32b enhanced the survival of benign and malignant T cells. (f, g) IL-32b induced the formation of large, activated CD14þ T cells. Similar results were observed in five additional donors. (h) The number of surviving malignant T cells was directly proportional to the number of IL-32beinduced large CD14þ cells. (i) IL-32b enhanced malignant T-cell survival by reducing apoptosis (detected by SYTOX Green). APC, antigen-presenting cell; cyt, cytokine; HTS, high throughput TCR sequencing.
Article Snippet: A total of 300,000e1,000,000 cells in 200 ml per well were cultured in round-bottom 96-well plates in the presence or absence of IL-2 (25 IU/ml, National Cancer Institute, Bethesda, MD), IL-32a (25 ng/ml; number 3040-IL-050, R&D Systems), IL-32b (25 ng/ml; number 6769-IL-025, R&D Systems), or IL-32g (25 ng/ml; number 4690-IL-025/CF, R&D Systems).
Techniques: High Throughput Screening Assay, Sequencing
