The capacity of HPVs, especially HR-HPVs, to undermine keratinocytes’ function as innate immune sentinels is crucial to this accomplishment. In the immune system, keratinocytes mediate by responding to cell stress, damage, and infection [65]. Additionally, pathogen recognition receptors (PRRs), ge...
Prominent nonviral causes of gastrointestinal disease include colibacillosis, coccidiosis, and enterotoxemia [4]. Coinfection by viral and nonviral pathogens is common and often cause more severe clinical signs than the viral pathogen alone would induce. Papillomavirus Oral papillomatosis in the ...
