In terms of the infection rates, it should be noted that a treatment with the endocytosis inhibitors resulted in a modest but significant reduction (p < 0.05) in the frequency of ANP+ and BNP+ cells Figure S2B), although this did not affect the gMFI expression levels of ANP and BNP proteins within NP+ cells (p > 0.05), with the exception of a modest decrease in BNP expression following treatment with Chlorpromazine (Figure S2C). Here, NPPB is linked to infection.
