Figure 2: Level of expression of integrin αV3 in PCF-BON samples. Average integrin αV3 expression in PCF-BON classified in different categories of R/S in response to FMDV subtype A24 or O1; above each rectangle is the percentage of PCF-BON in each R/S category. p: statistically significant differences between two categories, p*: statistically significant difference between the three categories. S: Susceptible, R: Resistant, VR: Very Resistant.
