Biological target:
Lamivudine sulfoxide, (R)- is a metabolite of Lamivudine; a potent nucleoside reverse transcriptase inhibitor and antiviral agent.
In vitro activity:
The aim of this study was to investigate if the nucleoside analogue lamivudine (LAM), a potent inhibitor of HBV replication, could restore the function of dendritic cells derived from patients with chronic hepatitis B (CHB) in an Asian population. Dendritic cells (DCs) derived from mononuclearcytes of patients with chronic HBV infection were cultured in the presence of IL-4, granulocyte-macrophage colony-stimulating factors (GM-CSF) and gradient concentrations of LAM (0-2 mmol/L). The expression of CD1α on DC treated with 0.5 mmol/L LAM (LAM-DC 0.5 mmol/L) was significantly higher than that of DC untreated with LAM (54.1 ± 4.21 vs 33.57 ± 3.14, P < 0.05), and so was the expression of CD83 (20.24 ± 2.51 vs 12.83 ± 2.12, P < 0.05) as well as the expression of HLA-DR (74.5 ± 5.16 vs 52.8 ± 2.51, P < 0.05). Compared with control group, LAM-DC group (0.5 mmol/L) secreted significantly more IL-12 (910 ± 91.5 vs 268 ± 34.3 pg/mL, P < 0.05), had lower levels of IL-6 in the culture supernatant (28 ± 2.6 vs 55 ± 7.36 pg/mL, P < 0.05), markedly enhanced the stimulatory capacity in the allogeneic mixed leukocyte reaction (MLR) (1.87 ± 0.6 vs 1.24 ± 0.51, P < 0.05). . This indicates that, in addition to its potent anti-HBV replication role, LAM is able to modify the biological activities of DCs derived from patients with CHB infection. Therefore, LAM can be a potential candidate as an immunoregulatory therapeutic remedy used in the treatment of patients with CHB infection.

In vivo activity:
The modulatory effects of 3TC (lamivudine) on Alu RNA-induced IL-18 and IL-1β expression were examined in mouse RPE (retinal pigment epithelium) by a subretinal injection of Alu RNA and concomitant intravitreal injection of equimolar 3TC or 3,4-(M)CA. Similar to effects in cultured human RPE cells, 3TC suppressed Alu RNA-induced IL-18 expression by 42.1 ± 8.7% (P = 0.006) and IL-1β expression by 57.8 ± 12.4% (P = 0.030) compared with that observed by 3,4-(M)CA treatment (Figs. 2A and B). Fundus imaging of mouse eye at 7 days after subretinal transfection and intravitreal injection of 3,4-(M)CA revealed substantial retinal/RPE degeneration, whereas intravitreal injection of 3TC substantially reduced Alu RNA-induced retinal/RPE degeneration (Figs. 2C and D). This data suggests that Alu RNA accumulation contributes to RPE cell senescence in age-related macular degeneration and that this pathogenic process can be suppressed by 3TC.
