Abstract:
The Herpes simplex virus ‐1 (HSV‐1) is responsible for several clinical manifestations in humans, including encephalitis. To induce encephalitis, C57BL/6 mice were inoculated with 10 4 plaque‐forming cells of HSV‐1 by the intracranial route. Met‐RANTES (regulated upon activation, normal T cell expressed and presumably secreted) (10 μg/mouse), a CC chemokine family receptor (CCR)1 and CCR5 antagonist, was given subcutaneously the day before, immediately after, and at days 1, 2, and 3 after infection. Treatment with Met‐RANTES had no effect on the viral titers. In contrast, intravital microscopy revealed that treatment with Met‐RANTES decreased the number of leukocytes adherent to the pial microvasculature at days 1 and 3 after infection. The levels of the chemokines CCL3, CCL5, CXCL1, and CXCL9 increased after infection and were enhanced further by the treatment with Met‐RANTES. Treatment with a polyclonal anti‐CCL5 antibody 2 h before the intravital microscopy decreased leukocyte adhesion in the microcirculation of infected mice. In conclusion, CCL5, a chemokine that binds to CCR1 and CCR5, is essential for leukocyte adhesion during HSV‐1 encephalitis. However, blocking of CCR1 and CCR5 did not affect HSV‐1 replication, suggesting that other immune mechanisms are involved in the process of infection control.
