Figure Legend Snippet: FIGURE 3. Rescue of defective degranulation of Munc13-4 KO NK cells with lentivirus expressing WT Munc13-4. Degranulation assays of Munc13-4 KO pri- mary NK cells that were transduced with lentivirus expressing EmGFP or WT Munc13-4–EmGFP. Degran- ulation was triggered with 2.5 mM ionomycin + 0.1 mM PMA for 6 h, and surface expression of CD107a was measured by FACS analysis. (A) Contour plots of FACS analysis illustrating induction of CD107a surface ex- pression in NK1.1+ primary NK cells that were trans- duced with EmGFP or WT Munc13-4 in unstimulated (top) and stimulated (bottom) condition. (B) Overlay of CD107a histograms in unstimulated (black) and stimu- lated (gray) NK cells. (C) A bar graph showing CD107a degranulation from EmGFP-rescued (white) and WT Munc13-4–rescued (black) KO NK cells. Error bars in- dicate SEM (n = 4).
Techniques Used: Expressing, Transduction
Figure Legend Snippet: FIGURE 4. Double and quadruple muta- tions in the C2 domains of Munc13-4 alters Ca2+ sensitivity of degranulation from NK cells. Degranulation assays of Munc13-4 KO primary NK cells that were transduced with lentivirus expressing EmGFP alone, WT, C2 domain double, or quadruple mu- tant Munc13-4–EmGFP. Degranulation was triggered with 2.5 mM ionomycin + 0.1 mM PMA for 6 h and surface expression of CD107a was measured by FACS analysis. (A) Contour plots of FACS analysis illus- trating induction of CD107a surface ex- pression in NK1.1+ primary NK cells in 2.2 mM (left) and 10 mM (right) extracel- lular Ca2+. (B) Overlay of CD107a histo- grams in 2.2 mM (black) and 10 mM (gray) NK cells. (C) A bar graph showing CD107a degranulation from rescued NK cells in 2.2 mM (white) and 10 mM (black). Error bars indicate SEM (n 5 4). *p , 0.05.

Figure Legend Snippet: FIGURE 5. Single-point mutations in the C2 domains of Munc13-4 alter Ca2+ sensi- tivity of degranulation from NK cells. De- granulation assays of Munc13-4 KO primary NK cells that were transduced with lentivirus expressing EmGFP alone, WT, or C2 domain single-mutant Munc13-4 EmGFP. Degranula- tion was triggered with 2.5 mM ionomycin + 0.1 mM PMA for 6 h and surface expression of CD107a was measured by FACS analysis. (A) Contour plots of FACS analysis illustrat- ing induction of CD107a surface expression in NK1.1+ primary NK cells in 2.2 mM (left) and 10 mM (right) extracellular Ca2+. (B) Overlay of CD107a histograms in 2.2 mM (black) and 10 mM (gray) NK cells. (C) A bar graph showing CD107a degranulation from rescued NK cells in 2.2 mM (white) and 10 mM (black).

Figure Legend Snippet: FIGURE 6. Mutations in C2 domains of Munc13-4 drastically reduces cytotoxicity of NK cells. (A) Control and Munc13-4 KO NK cells (effector cells) were incubated with Calcein Blue AM–loaded K562 cells (target cells) at indicated E:T ratios for 4 h, and the amount of Calcein Blue AM was measured. Percentage of lysis was calculated by dividing the amount of Calcein Blue AM by the total amounts (2% Triton X-100) 3 100%. Error bars indicate SEM (n = 12). (B) Cytotoxicity assay of Munc13-4 KO NK cells that are transduced with lentivirus expressing EmGFP, WT, or indicated C2 domain mutants. E:T ratios were 50:1 and 12.5:1. Error bars indicate SEM (n = 9).
