Figure 7: The effect of CB2R modulation on the expression of immunomodulatory genes in young and aged mice.

To evaluate the effect of CBR2 modulation on expression of immunomodulatory genes in vaccinated young and aged mice, splenocytes from mice treated with either vehicle, 10 mg/kg AM630 or 3 mg/kg AM1241 from days 0–4 post-immunization were harvested and single-cell suspension prepared at end point of vaccination at day 28 post-vaccination. QPCR was performed on splenocytes using specific primers to determine the levels of immunomodulatory genes (a,g) MHC II, (b,h) CXCR5, (c,i) CCR7, (d,j) L-Selectin, (e,k) SWAP70 and (f,l) Connexin43. Gene expression levels were normalized to GAPDH. Results are expressed as mean ± SEM; n = 6–8/group. Statistical analysis conducted by nonparametric Mann-Whitney U test, *p < 0.05 or **p < 0.01, all samples compared to vehicle control.
