Yet, in cutaneous squamous cell carcinoma, evidence on the collective expression patterns of these inhibitory immune checkpoints is scarce. Complete tumour sections of 36 cutaneous squamous cell carcinoma, 5 cutaneous metastases and 9 keratoacanthomas, a highly-differentiated, squamoproliferative tumour, with disparately benign biologic behaviour, were evaluated by immunohistochemistry for expression of programmed cell death ligand 1 (Tumor Proportion Score, Immune Cell Score), TIGIT, CD155 and CD8+ immune infiltrates. Unlike keratoacanthomas, cutaneous squamous cell carcinoma displayed a strong positive correlation of programmed cell death ligand 1 Tumor Proportion Score and CD115 expression (p < 0.001) with significantly higher programmed cell death ligand 1 Tumor Proportion Score (p < 0.001) and CD155 expression (p < 0.01) in poorly differentiated G3-cutaneous squamous cell carcinoma compared with keratoacanthomas. TIGIT+ infiltrates were significantly increased in programmed cell death ligand 1 Immune Cell Score positive primary tumours (p = 0.05). Yet, a strong positive correlation of TIGIT expression with CD8+ infiltrates was only detected in cutaneous squamous cell carcinoma (p < 0.01), but not keratoacanthomas. Providing a comprehensive overview on the collective landscape of inhibitory immune checkpoint expression, this study reveals associations of novel inhibitory immune checkpoint with CD8+ immune infiltrates and tumour differentiation and highlights the TIGIT/CD155 axis as a potential new target for cutaneous squamous cell carcinoma immunotherapy. 000287642 536__ $$0G:(DE-HGF)POF4-313$$a313 - Krebsrisikofaktoren und Prävention (POF4-313)$$cPOF4-313$$fPOF IV$$x0 000287642 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000287642 7001_ $$0P:(DE-He78)92820b4867c955a04f642707ecf35b40$$aEdelmann, Dominic$$b1$$udkfz 000287642 7001_ $$aAlbrecht, Thomas$$b2 000287642 7001_ $$aBrobeil, Alexander$$b3 000287642 7001_ $$aLabrenz, Jannik$$b4 000287642 7001_ $$aJohanning, Moritz$$b5 000287642 7001_ $$aSchlenk, Richard F$$b6 000287642 7001_ $$aGoeppert, Benjamin$$b7 000287642 7001_ $$aEnk, Alexander H$$b8 000287642 7001_ $$aToberer, Ferdinand$$b9 000287642 773__ $$0PERI:(DE-600)1492617-9$$a10.2340/actadv.v104.13381$$gVol. 104, p. adv13381 -$$padv13381 -$$tActa dermato-venereologica$$v104$$x0001-5555$$y2024 000287642 909CO $$ooai:inrepo02.dkfz.de:287642$$pVDB 000287642 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)92820b4867c955a04f642707ecf35b40$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000287642 9131_ $$0G:(DE-HGF)POF4-313$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vKrebsrisikofaktoren und Prävention$$x0 000287642 9141_ $$y2024 000287642 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bACTA DERM-VENEREOL : 2022$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2023-01-19T09:14:05Z 000287642 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2023-01-19T09:14:05Z 000287642 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Anonymous peer review$$d2023-01-19T09:14:05Z 000287642 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2023-08-25 000287642 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2023-08-25 000287642 9201_ $$0I:(DE-He78)C060-20160331$$kC060$$lC060 Biostatistik$$x0 000287642 980__ $$ajournal 000287642 980__ $$aVDB 000287642 980__ $$aI:(DE-He78)C060-20160331 000287642 980__ $$aUNRESTRICTED
