A) Secreted TMPRSS2 and SLPI. B) Densitometric analysis to quantitate the amounts of secreted TMPRSS2 and SLPI in all samples. Data were expressed as levels of SLPI: TMPRSS2 ratio for each subject. C) Representative immunoblot showing cleavage of viral HA. Densitometry was used to quantitate the amounts of cleaved HA2 protein. Numbers represent relative levels of HA2 in each sample. D) Viral titer indicated in log TCID50. Unpaired Student’s t-test was used for determination of statistically significant differences. Asterisk indicates statistical significance between HVs and AAs; p < 0.05.
