    Cell-to-cell contact and soluble priming factors on MDM are modulated by HIV-1 infection as well as NK cells (A) Experimental setup of MDM-NK cell co-culture. After 5 days of HIV-1 infection or 24 h of LPS/IFNγ-stimulation of MDM, autologous NK cells were added to the culture at a ratio of 1:1, according to the seeding density of CD14 + monocytes. After 24 h, NK-cell ligand expression on MDM was assessed. (B–D) MDM infection frequencies (CD4 − p24+ cells) after HIV-1 infection with 89.6 and THRO.c with and without 24 h NK-cell co-culture are depicted. Differences in infection frequencies between MDM with and without NK cell co-culture for each strain were analyzed using the Wilcoxon signed-rank test (89.6: n = 8; THRO.c: n = 9). Representative histogram of HLA-E (C) and HLA-ABC (D) surface expression on unstimulated MDM (left). Median fluorescence intensity (MdFI) of HLA-E and HLA-ABC on unstimulated, HIV-1-infected and bystander MDM is compared between MDM cultured without (NK-) or with NK cells (NK+) (right). Differences in MdFI values between infected and bystander MDM and between NK- and NK + MDM in each strain were analyzed using the Wilcoxon signed-rank test with FDR correction (Original Benjamini and Hochberg) (unstained (us): n = 19; unstim.: n = 21; 89.6 NK+: n = 14; 89.6 NK-: n = 9; THRO.c NK+: n = 11; THRO.c NK-: n = 10).

Soluble IL-15 (F), IL-23 (G), and IL-18 (H, left) concentrations in MDM-NK cell co-culture supernatants from HIV-1 89.6, THRO.c and LPS/IFNγ conditions compared to unstimulated co-cultures. Differences in cytokine concentrations to unstimulated were analyzed using the Wilcoxon signed-rank test with FDR correction (Original Benjamini and Hochberg) (89.6: n = 4; THRO.c: n = 9; LPS/IFNγ: n = 10). Only significant p -values are shown. (H, right) Relation between IL-18 concentrations in 89.6- and THRO.c-infected MDM-NK co-cultures and the corresponding infection frequency. Spearman correlation coefficient was used to analyze the correlation between infection frequency and cytokine concentration (89.6: n = 4; THRO.c: n = 9). All data are shown as median ± IQR with each dot representing one biological replicate.

    Cell-to-cell contact and soluble priming factors on MDM are modulated by HIV-1 infection as well as NK cells (A) Experimental setup of MDM-NK cell co-culture. After 5 days of HIV-1 infection or 24 h of LPS/IFNγ-stimulation of MDM, autologous NK cells were added to the culture at a ratio of 1:1, according to the seeding density of CD14 + monocytes. After 24 h, NK-cell ligand expression on MDM was assessed. (B–D) MDM infection frequencies (CD4 − p24+ cells) after HIV-1 infection with 89.6 and THRO.c with and without 24 h NK-cell co-culture are depicted. Differences in infection frequencies between MDM with and without NK cell co-culture for each strain were analyzed using the Wilcoxon signed-rank test (89.6: n = 8; THRO.c: n = 9). Representative histogram of HLA-E (C) and HLA-ABC (D) surface expression on unstimulated MDM (left). Median fluorescence intensity (MdFI) of HLA-E and HLA-ABC on unstimulated, HIV-1-infected and bystander MDM is compared between MDM cultured without (NK-) or with NK cells (NK+) (right). Differences in MdFI values between infected and bystander MDM and between NK- and NK + MDM in each strain were analyzed using the Wilcoxon signed-rank test with FDR correction (Original Benjamini and Hochberg) (unstained (us): n = 19; unstim.: n = 21; 89.6 NK+: n = 14; 89.6 NK-: n = 9; THRO.c NK+: n = 11; THRO.c NK-: n = 10).

Soluble IL-15 (F), IL-23 (G), and IL-18 (H, left) concentrations in MDM-NK cell co-culture supernatants from HIV-1 89.6, THRO.c and LPS/IFNγ conditions compared to unstimulated co-cultures. Differences in cytokine concentrations to unstimulated were analyzed using the Wilcoxon signed-rank test with FDR correction (Original Benjamini and Hochberg) (89.6: n = 4; THRO.c: n = 9; LPS/IFNγ: n = 10). Only significant p -values are shown. (H, right) Relation between IL-18 concentrations in 89.6- and THRO.c-infected MDM-NK co-cultures and the corresponding infection frequency.

All data are shown as median ± IQR with each dot representing one biological replicate.
