Understanding how diverse pulmonary immune cells respond to these challenges is critical for advancing respiratory disease research and identifying appropriate therapeutic interventions. Flow cytometry remains a cornerstone of immune profiling, and advances in high\u2010parameter spectral cytometry have significantly expanded its analytical capabilities. However, challenges, such as poor tissue dissociation, spectral overlap, and loss of spatial information, can hinder the comprehensive interpretation of the lung environment. To address these limitations, we developed an optimized spectral flow cytometry platform, utilizing 5\u2010laser Cytek Aurora spectral cytometers, for deep immunophenotyping of murine lung tissue. Our approach integrates in vivo CD45 antibody labeling\u2014administered intravenously and oropharyngeally\u2014to distinguish circulating, airway, and interstitial immune populations, preserving spatial context in single\u2010cell suspensions. We utilize complementary 25+ parameter panels targeting myeloid and lymphoid compartments, built on a shared backbone to enable consistent classification across datasets. Refined tissue processing protocols support optimal recovery of representative lung cell populations, and overnight intracellular staining enhances marker resolution. Using this platform, we reliably resolve stromal, endothelial, and epithelial cells alongside immune subsets\u2014including macrophages, monocytes, dendritic cells, eosinophils, neutrophils, T and B cells, innate lymphoid cells (ILCs), and natural killer (NK) cells\u2014subclassified by activation, function, and tissue residency. Validation with an influenza A virus model confirmed expected dynamic immune responses and revealed previously unrecognized populations. This spatially informed approach enables high\u2010resolution interrogation of pulmonary immunity in health and disease. \u00a9 2025 Wiley Periodicals LLC.<\/jats:p>\n                  <jats:p>\n                    <jats:bold>Basic Protocol 1<\/jats:bold>\n                    : Differential in vivo labeling for spatial profiling of pulmonary immune cells by spectral cytometry\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Basic Protocol 2<\/jats:bold>\n                    : Preparation of single\u2010cell suspensions from murine lung tissue for spectral cytometric analysis of immune cell populations\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Basic Protocol 3<\/jats:bold>\n                    : Optimized workflow and spectral flow cytometry panels for profiling of pulmonary immune cell populations in a single\u2010cell suspension\n                  <\/jats:p>","DOI":"10.1002\/cpz1.70276","type":"journal-article","created":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T15:49:47Z","timestamp":1764949787000},"source":"Crossref","is-referenced-by-count":1,"title":["Spatially Resolved Immune Profiling of the Murine Lung Using In Vivo Labeling and Spectral Cytometry"],"prefix":"10.1002","volume":"5","author":[{"given":"Rebecca","family":"Palmer","sequence":"first","affiliation":[{"name":"Malaghan Institute of Medical Research  Wellington New Zealand"},{"name":"University of Otago Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine R.","family":"Pilkington","sequence":"additional","affiliation":[{"name":"Malaghan Institute of Medical Research  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kit","family":"Moloney\u2010Geany","sequence":"additional","affiliation":[{"name":"Malaghan Institute of Medical Research  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathryn E.","family":"Hally","sequence":"additional","affiliation":[{"name":"University of Otago Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1238-1552","authenticated-orcid":false,"given":"Kerry L.","family":"Hilligan","sequence":"additional","affiliation":[{"name":"Malaghan Institute of Medical Research  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,5]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nprot.2014.005"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1084\/jem.175.4.1143"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2020.583042"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.3390\/cells13201677"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.immuni.2020.04.005"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/cyto.a.24828"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.aau0964"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41392\u2010023\u201001452\u20101"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chom.2018.08.001"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tox.2009.02.007"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/cpz1.657"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/cpz1.222"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.3389\/fcimb.2020.00425"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-0716-3738-8"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/cyto.a.24555"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.immunol.26.021607.090331"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2023.11.032"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/cyto.a.24841"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1080\/01902140600817465"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/8028725"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.coviro.2024.101397"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciimmunol.abj5761"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/cyto.a.20092"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cll.2007.05.002"},{"key":"e_1_2_9_26_1","doi-asserted-by":"crossref","unstructured":"McInnes L.
