Feline herpesvirus type 1 (FHV-1) is an enveloped dsDNA virus belonging to the Herpesviridae family and is considered one of the two primary viral etiological factors of feline upper respiratory tract disease. In this study, we investigated the entry of FHV-1 into host cells using two models: the AK-D cell line and primary feline skin fibroblasts (FSFs). We employed confocal microscopy, siRNA silencing, and selective inhibitors of various entry pathways. Our observations revealed that the virus enters cells via pH and dynamin-dependent endocytosis, as the infection was significantly inhibited by NH4Cl, bafilomycin A1, dynasore, and mitmab. Additionally, genistein, nystatin, and filipin treatments, siRNA knock-down of caveolin-1, as well as FHV-1 and caveolin-1 colocalization suggest the involvement of caveolin-mediated endocytosis during the entry process. siRNA knock-down of clathrin heavy chain and analysis of virus particle colocalization with clathrin indicated that clathrin-mediated endocytosis also takes part in the primary cells. This is the first study to systematically examine FHV-1 entry into host cells, and for the first time, we describe FHV-1 replication in AK-D and FSFs. IMPORTANCE Feline herpesvirus 1 (FHV-1) is one of the most prevalent viruses in cats, causing feline viral rhinotracheitis, which is responsible for over half of viral upper respiratory diseases in cats and can lead to ocular lesions resulting in loss of sight. Although the available vaccine reduces the severity of the disease, it does not prevent infection or limit virus shedding. Despite the clinical relevance, the entry mechanisms of FHV-1 have not been thoroughly studied. Considering the limitations of commonly used models based on immortalized cells, we sought to verify our findings using primary feline skin fibroblasts, the natural target for infection in cats.
