TTV species diversity

1. TTV species diversity is associated with PARP1 in humans.

   “PARP-1 expression and activity increased in individuals with higher TTV diversity, particularly in the presence of TTV9 and TTV20.”

1. TTV species diversity is associated with immune impairment risk in humans.

   “Increased TTV species number correlated with higher TTV load, elevated CMV IgG levels, and greater immune impairment risk.”

1. Immune impairment is associated with TTV species diversity in humans.

   “Alpha- and beta-diversity analyses showed the highest TTV species diversity in Cohort 1 C, with significant cohort-dependent differences and partially cohort-specific clustering patterns.”
