Figure 2From: Inhibition of HSP90 attenuates porcine reproductive and respiratory syndrome virus production in vitroHSP90 inhibitors reduced PRRSV production. (A) MARC-145 cells and (B) PAMs were infected and treated with different concentrations of drugs. The culture supernatants were collected at 24 h.p.i and viral titers were determined by calculating CCID50. Data are mean ± SD, n = 3, and significant differences compared with DMSO (in MARC-145 cells) or no drug (in PAMs) treatment group, respectively, are denoted by *(P < 0.05).Back to article page
