Despite considerable research, fully understanding HSK and eliminating it remains challenging due to a lack of comprehensive analysis of HSV-1-infected immune cells in both corneas and trigeminal ganglia (TG). We engineered a recombinant HSV-1 expressing green fluorescent protein (GFP) in the virulent McKrae virus strain that does not require corneal scarification for efficient virus replication (GFP-McKrae). Next-generation sequencing (NGS) analysis, along with\n              <jats:italic>in vitro<\/jats:italic>\n              and\n              <jats:italic>in vivo<\/jats:italic>\n              assays, showed that GFP-McKrae virus was similar to WT-McKrae virus. Furthermore, corneal cells infected with GFP-McKrae were quantitatively analyzed using image mass cytometry (IMC). The single-cell reconstruction data generated cellular maps of corneas based on the expression of 25 immune cell markers in GFP-McKrae-infected mice. Corneas from mock control mice showed the presence of T cells and macrophages, whereas corneas from GFP-McKrae-infected mice on days 3 and 5 post-infection (PI) exhibited increased immune cells. Notably, on day 3 PI, increased GFP expression was observed in closely situated clusters of DCs, macrophages, and epithelial cells. By day 5 PI, macrophages and T cells became prominent. Finally, immunostaining methods detected HSV-1 or GFP and gD proteins in latently infected TG. This study presents a valuable strategy for identifying cellular spatial associations in viral pathogenesis and holds promise for future therapeutic applications.\n            <\/jats:p>\n            <jats:sec>\n              <jats:title>IMPORTANCE<\/jats:title>\n              <jats:p>The goal of this study was to establish quantitative approaches to analyze immune cell markers in HSV-1-infected intact corneas and trigeminal ganglia from primary and latently infected mice. This allowed us to define spatial and temporal interactions between specific immune cells and their potential roles in virus replication and latency. To accomplish this important goal, we took advantage of the utility of GFP-McKrae virus as a valuable research tool while also highlighting its potential to uncover previously unrecognized cell types that play pivotal roles in HSV-1 replication and latency. Such insights will pave the way for developing targeted therapeutic approaches to tackle HSV-1 infections more effectively.<\/jats:p>\n            <\/jats:sec>\n          <\/jats:sec>","DOI":"10.1128\/mbio.01454-24","type":"journal-article","created":{"date-parts":[[2024,9,9]],"date-time":"2024-09-09T13:02:12Z","timestamp":1725886932000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["A novel GFP-based strategy to quantitate cellular spatial associations in HSV-1 viral pathogenesis"],"prefix":"10.1128","volume":"15","author":[{"given":"Deepak","family":"Arya","sequence":"first","affiliation":[{"name":"Center for Neurobiology and Vaccine Development, Ophthalmology Research, Department of Surgery, Cedars-Sinai Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6844-659X","authenticated-orcid":false,"given":"Ujjaldeep","family":"Jaggi","sequence":"additional","affiliation":[{"name":"Center for Neurobiology and Vaccine Development, Ophthalmology Research, Department of Surgery, Cedars-Sinai Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaohui","family":"Wang","sequence":"additional","affiliation":[{"name":"Center for Neurobiology and Vaccine Development, Ophthalmology Research, Department of Surgery, Cedars-Sinai Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kati","family":"Tormanen","sequence":"additional","affiliation":[{"name":"Center for Neurobiology and Vaccine Development, Ophthalmology Research, Department of Surgery, Cedars-Sinai Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingtian","family":"Che","sequence":"additional","affiliation":[{"name":"Applied Genomics, Computation, and Translational Core, Cedars-Sinai Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simeon","family":"Mahov","sequence":"additional","affiliation":[{"name":"Applied Genomics, Computation, and Translational Core, Cedars-Sinai Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Jin","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Oregon State University, College of Veterinary Medicine, Corvallis, Oregon, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3291-1995","authenticated-orcid":true,"given":"Homayon","family":"Ghiasi","sequence":"additional","affiliation":[{"name":"Center for Neurobiology and Vaccine Development, Ophthalmology Research, Department of Surgery, Cedars-Sinai Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0039-6257(76)90087-4"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0025-7125(16)31162-2"},{"key":"e_1_3_4_4_2","first-page":"S38","article-title":"The current trend in genital herpes.
