Figure Lengend Snippet: Data were obtained from 54 cells across 28 rats (Responders: n=20 cells/[8] rats; Non-responders: n=21 cells/[9] rats; Mild Responders: n=7 cells/[5] rats; Naïve: n=6 cells/[4] rats). Dose-response effects (1, 5, 10 μM; averaged over 12 min) in responders versus non-responders: ( A ) Frequency, significantly increased only in responders at 10 μM (*P = 0.0263). ( B ) Amplitude, significantly decreased only in responders at 10 μM (**P = 0.0034). ( C ) Rise time, significantly increased in non-responders at all doses (**P < 0.05 to ***P < 0.01) and in responders at 5 μM and 10 μM (*P < 0.05). ( D ) Decay time, significantly increased only in non-responders at 10 μM (*P = 0.0420). Effects at 10 μM across all groups (ethanol-naïve controls, non-responders, mild responders, responders): ( E ) Frequency, significantly increased only in responders (*P = 0.0263). ( F ) Amplitude, significantly decreased only in responders (**P = 0.0034). ( G ) Rise time, significantly increased in non-responders (*P = 0.0328) and responders (*P = 0.0467). ( H ) Decay time, significantly increased only in non-responders (*P = 0.0420). Temporal dynamics at 10 μM: ( I ) Representative sIPSC traces shown for non-responders, mild responders, and responders. ( J ) Timeline of frequency changes (3-min bins), with two-way ANOVA showing a significant time × group interaction (P < 0.0001); Bonferroni’s post-hoc tests indicated differences at 9 minutes and 12 minutes (*P < 0.05 vs non-responders and # P < 0.05 vs mild responders). ( K ) Frequency per bin relative to baseline for each group, with significant elevations in non-responders at 3 minutes (*P = 0.0150), mild responders at 6 minutes (*P = 0.0281), and responders at 9 minutes (*P = 0.0120) and 12 minutes (**P = 0.0080). All data are presented as mean ± SEM (normalized to baseline [100%]); statistical analyses used one-sample t-tests against 100% unless otherwise noted.

Figure Lengend Snippet: Ethanol escalation and reduction by ivermectin. Data depict a cohort of n=32 (16 males, blue circles; 16 females, pink circles) tested in a Latin square design. ( A ) Temporal profile of operant ethanol intake (10% v/v; 0.1 mL/reinforcer). Highlighting indicates post-vapor sessions. ANOVA showed a main effect of time (P<0.0001); Bonferroni’s post-hocs revealed increases from the last pre-vapor session (session 10) to post-vapor sessions 17–22 (**P<0.01, *P<0.001). ( B ) Average intake during the final three pre-vapor vs. post-vapor sessions (paired t-test: P<0.0001). ( C ) Blood alcohol levels (BALs) across vapor weeks (Time effect: **P=0.0056); progressive increases observed from week 5 vs. weeks 6–10 (P<0.0001). ( D ) Dose-dependent reduction of ethanol intake by ivermectin (0–10 mg/kg, i.p., administered −4 h). ANOVA showed a significant treatment effect (P=0.0002); post-hocs confirmed reductions at 5 and 10 mg/kg vs. vehicle (P<0.01). ( E ) Number of rewards earned (Treatment effect: P=0.0078; * P<0.05 vs. vehicle at 5 and 10 mg/kg). ( F ) Water rewards (non-specific control) were unaffected (P=0.57). ( G ) Ethanol intake separated by sex. Two-way ANOVA showed main effects of dose (P=0.0001) and sex (P=0.0011) but no interaction. ( H ) Males only: significant treatment effect (P=0.0073; * P<0.05 at 5 and 10 mg/kg). ( I ) Females only: significant treatment effect (P=0.0279; * P<0.05 at 10 mg/kg). Data expressed as mean ± SEM.

Figure Lengend Snippet: All panels depict data from the cohort (n = 32; 16 males, 16 females) stratified into non-responders (n = 11), mild responders (n = 10), and responders (n = 11) based on averaged Z-scores of deltas decrease in intake across ivermectin doses. ( A ) Averaged responsivity Z-scores by group, with one-way ANOVA showing a significant group effect (P < 0.0001). Bonferroni’s post-hoc tests indicated differences between non-responders and responders (****P < 0.0001) and mild responders and responders (***P = 0.0003). Data are presented as mean ± SEM. ( B ) Correlation between baseline post-vapor ethanol intake Z-scores and responsivity Z-scores (linear regression: R 2 = 0.3334, P = 0.0007). ( C ) Average blood alcohol levels (BALs; mg/dL) during vapor exposure showed no group differences (ANOVA: P = 0.4460). Data are presented as mean ± SEM. ( D ) Ethanol intake (g/kg) across doses in non-responders showed no significant treatment effect (ANOVA: P = 0.0774). Data presented as mean ± SEM. ( E ) Ethanol intake in mild responders exhibited a significant treatment effect (ANOVA: P = 0.0091) and post-hoc tests showing reductions at 5 and 10 mg/kg (*P < 0.05). Data are presented as mean ± SEM. ( F ) Ethanol intake in responders demonstrated a significant treatment effect (ANOVA: P < 0.0001) and post-hoc tests indicating reductions at all doses (*P < 0.05, **P < 0.01, ***P < 0.001). Data are presented as mean ± SEM. In all panels, individual data points are shown as blue dots (males) and pink dots (females).

(B) Motility dose response curves 24 hours and 48 hours after treatment with ivermectin (IVM), diethylcarbamazine (DEC), albendazole sulfoxide (AZS), and emodepside (EMO), with dashed lines showing experimental IC50 (color) and therapeutic plasma C max (black) values. Controls include mf treated with 1% DMSO and heat killed (HK) mf. (C) Viability (CellTox Green) fluorescence readings on a log 10 scale across treatment concentrations compared to DMSO and HK controls. (D) Representative brightfield (top row) and CellTox stained (bottom row) images of control and drug treated mf. (E) Motility dose response curves for drug treatment combinations. IVM treatment combined with AZS (500nM or 10µM) or DEC (15µM or 30µM), and EMO treatment combined with 15µM or 30µM DEC. Drug combination IC50s are marked as solid colored lines and IVM plasma C max values as dashed black lines. Individual drug IC50s from (B) are also shown (IVM: purple, EMO: green). Each plot point represents measurements for a plate well containing 1000 mf; each condition was performed across at least four technical replicates (wells) per experiment and each experiment was repeated for at least three biological replicates (parasite cohorts).
