Gi designer receptors exclusively activated by designer drugs (DREADD) inhibition of microglia blocks alcohol-induced neuronal cell death. A – D: Organotypic brain slice cultures (OBSCs) <t>from</t> <t>CX3CR1.Cre</t> <t>ERT2</t> .hM4di.mCitrine (+/–) mice were used to assess the role of microglia on neuronal death ex vivo. A: Representative image with or without addition of 4-hydroxy-tamoxifen (4-OH-TAM; 10 ng/mL) to induce Cre recombination, which caused a robust increase in mCitrine within ionized calcium-binding adapter molecule 1 (Iba-1) + microglia, consistent with microglial DREADD expression. Arrowheads denote colocalization between Iba-1 and mCitrine. B: Representative images of propidium iodide (PI) labeling of cell death in OBSC in response to ethanol. C: Ethanol (EtOH; 100 mmol/L; 4 days) caused a robust increase in cell death 24 hours into withdrawal, which was significantly blocked by microglial Gi signaling induced by clozapine N-oxide [CNO; two-way analysis of variance (ANOVA) main effect of ethanol F 1,20 = 11.37, P = 0.003; Sidak post test]. D and E: Induction of hM4Di Gi DREADD inhibition of microglia in vivo . CX3CR1.Cre ERT2 .hM4Di (+/–) mice received 10 days of water or binge ethanol (5 g/kg per day; intragastric) with or without CNO (3 mg/kg; intraperitoneally; 10 hours after ethanol). Assessments were performed 24 hours following the final treatment. D: Representative images of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) cell death stain in orbitofrontal cortex. E: Ethanol increased TUNEL + cell death by approximately threefold, which was prevented by Gi DREADD inhibition of proinflammatory microglia (two-way ANOVA, EtOH × CNO interaction F 1,16 = 8.5, P = 0.01; Sidak post test).

Gi designer receptors exclusively activated by designer drugs inhibition of microglia fails to attenuate alcohol-induced negative affect in males. A: Experimental design. Male CX3CR1.Cre ERT2 .hM4Di (+/–) mice received 10 days of water or binge ethanol (EtOH; 5 g/kg per day; intragastric) with or without clozapine N-oxide (CNO) 10 hours after treatment. Mice underwent open field testing for anxiety-like behavior 3 days into withdrawal and conditioned fear for acquisition and extinction at 34 days into abstinence. B: hM4di expression was measured by RT-PCR. Males showed approximately 25% of the level hM4di expression as females. t- Test was used. C and D: Microglial inhibition failed to prevent the induction of anxiety-like behavior caused by alcohol seen change in the distance traveled in the center of the open field [one-way analysis of variance (ANOVA) F 2,18 = 2.0, P = 0.16; C ] and a reduction in the time spent in the center of the open field (one-way ANOVA F 2,17 = 3.99, P = 0.038; Sidak post test; D ).

Gi designer receptors exclusively activated by designer drugs (DREADD) inhibition of microglia attenuates alcohol-induced negative affect in females. A: Experimental design. Female CX3CR1.Cre ERT2 .hM4Di (+/–) mice received 10 days of water or binge ethanol (EtOH; 5 g/kg per day; intragastric) with or without clozapine N-oxide (CNO) 10 hours after treatment. Mice underwent open field testing for anxiety-like behavior 3 days into withdrawal and conditioned fear for acquisition and extinction at 34 days into abstinence. B and C: Microglial inhibition prevented the induction of anxiety-like behavior caused by alcohol seen as a reduction in the distance traveled in the center of the open field [one-way analysis of variance (ANOVA) F 2,20 = 3.95, P = 0.036; Sidak post test; B ] and reduced time spent in the center of the open field (one-way ANOVA F 2,20 = 7.1, P = 0.0046; Sidak post test; C ). D: Microglial inhibition prevented the trend toward a reduction in fine motor movement in the open field caused by ethanol (one-way ANOVA F 2,21 = 2.16, P = 0.14). E: Ethanol had no impact on conditioned fear learning acquisition. F: In contextual fear memory assessments, ethanol increased freezing in the last minute of assessment that was prevented by microglial inhibition with CNO (two-way ANOVA time × treatment F 8,84 = 3.7, P < 0.0001; Sidak post test). G: Ethanol disrupted the extinction of conditioned fear memory, which was restored by microglial inhibition (one-way repeated measures ANOVAs: control F 2.4,13.5 = 2.1, P = 0.16; ethanol F 2.8,19.8 = 0.9, P = 0.45; ethanol + CNO F 3.0,17.6 = 6.6, P = 0.0035). H: The persistent induction of multiple proinflammatory genes in the cortex 5 weeks into abstinence was prevented by Gi DREADD inhibition of microglia (two-way ANOVA F 2,231 = 6.921, P = 0.001). I: A negative correlation between IFNA gene expression and time spent in the center of the open field was found. IFN gene expression failed a normality test; thus, a Spearman correlation coefficient was calculated. R = -0.45, P = 0.039.

Figure Lengend Snippet: Gi designer receptors exclusively activated by designer drugs (DREADD) inhibition of microglia attenuates alcohol-induced negative affect in females. A: Experimental design. Female CX3CR1.Cre ERT2 .hM4Di (+/–) mice received 10 days of water or binge ethanol (EtOH; 5 g/kg per day; intragastric) with or without clozapine N-oxide (CNO) 10 hours after treatment. Mice underwent open field testing for anxiety-like behavior 3 days into withdrawal and conditioned fear for acquisition and extinction at 34 days into abstinence. B and C: Microglial inhibition prevented the induction of anxiety-like behavior caused by alcohol seen as a reduction in the distance traveled in the center of the open field [one-way analysis of variance (ANOVA) F 2,20 = 3.95, P = 0.036; Sidak post test; B ] and reduced time spent in the center of the open field (one-way ANOVA F 2,20 = 7.1, P = 0.0046; Sidak post test; C ). D: Microglial inhibition prevented the trend toward a reduction in fine motor movement in the open field caused by ethanol (one-way ANOVA F 2,21 = 2.16, P = 0.14). E: Ethanol had no impact on conditioned fear learning acquisition. F: In contextual fear memory assessments, ethanol increased freezing in the last minute of assessment that was prevented by microglial inhibition with CNO (two-way ANOVA time × treatment F 8,84 = 3.7, P < 0.0001; Sidak post test). G: Ethanol disrupted the extinction of conditioned fear memory, which was restored by microglial inhibition (one-way repeated measures ANOVAs: control F 2.4,13.5 = 2.1, P = 0.16; ethanol F 2.8,19.8 = 0.9, P = 0.45; ethanol + CNO F 3.0,17.6 = 6.6, P = 0.0035). H: The persistent induction of multiple proinflammatory genes in the cortex 5 weeks into abstinence was prevented by Gi DREADD inhibition of microglia (two-way ANOVA F 2,231 = 6.921, P = 0.001). I: A negative correlation between IFNA gene expression and time spent in the center of the open field was found. IFN gene expression failed a normality test; thus, a Spearman correlation coefficient was calculated. R = -0.45, P = 0.039. N = 8 female water + vehicle, ethanol + vehicle, and ethanol + CNO ( B – I ). ∗ P < 0.05, ∗∗ P < 0.01. GFAP, glial fibrillary acidic protein; NS, not significant; TNF, tumor necrosis factor.
