Dilin komplike onkolojik mekanizmalar\u0131 anlamada yeni bir d\u00f6nemi i\u015faret eden bir ara\u015ft\u0131rma, a\u011f\u0131z alt\u0131 submukozal fibrozdan (OSF) kaynaklanan oral skuam\u00f6z h\u00fccreli karsinomda (OSCC) dikkat \u00e7ekici bir imm\u00fcnosupresif t\u00fcm\u00f6r mikro\u00e7evresi profilini ortaya koydu. Bu \u00e7al\u0131\u015fma, INHBA pozitif makrofajlar ve pro-inflamatuar kanser ili\u015fkili fibroblastlar\u0131n (CAF\u2019lar) \u00f6zg\u00fcn alt tiplerinin, kanser ilerlemesi ve ba\u011f\u0131\u015f\u0131kl\u0131k sisteminden ka\u00e7\u0131\u015fta kritik rol oynad\u0131\u011f\u0131n\u0131 vurguluyor. \u00d6zellikle OSF\u2019li hastalardan geli\u015fen ODSCC\u2019de, t\u00fcm\u00f6r ortam\u0131nda var olan h\u00fccresel ve molek\u00fcler dinamiklerin, mevcut imm\u00fcnoterapi yakla\u015f\u0131mlar\u0131n\u0131n etkinli\u011fini s\u0131n\u0131rlayabilece\u011fi ortaya kondu.<\/p>\n
A\u011f\u0131z submukozal fibroz, \u00f6zellikle b\u00f6lgede yayg\u0131n olan betel cevizi t\u00fcketimiyle ili\u015fkilendirilen, potansiyel malign bir durum olarak tan\u0131mlanmakta. Bu rahats\u0131zl\u0131k, ODSCC olarak adland\u0131r\u0131lan, OSF ge\u00e7mi\u015fi olan hastalardan geli\u015fen \u00f6zg\u00fcn bir OSCC alt tipini tetikliyor. \u00d6nceki \u00e7al\u0131\u015fmalar ODSCC\u2019nin molek\u00fcler ve metabolik \u00f6zelliklerini incelemi\u015f olsa da, t\u00fcm\u00f6r mikro\u00e7evresinde hangi h\u00fccre tiplerinin bu imm\u00fcnosupresif a\u011f\u0131 olu\u015fturdu\u011fu belirsizdi. Son ara\u015ft\u0131rma, bu bo\u015flu\u011fu ileri teknoloji tek h\u00fccre RNA dizileme ve mek\u00e2nsal transkriptomik y\u00f6ntemlerle dolduruyor.<\/p>\n
Zhao ve arkada\u015flar\u0131, ODSCC t\u00fcm\u00f6r mikro\u00e7evresini \u00e7ok detayl\u0131 bir bi\u00e7imde incelemek i\u00e7in, GEO veri taban\u0131ndan eri\u015filen kamusal veriler ve immunofloresan boyama tekniklerini kulland\u0131. Analizler, g\u00fc\u00e7l\u00fc bir T h\u00fccresi t\u00fckenmi\u015fli\u011fi ve reg\u00fclat\u00f6r T h\u00fccresi (Treg) art\u0131\u015f\u0131yla birlikte, sitotoksik T lenfositlerinde azalma oldu\u011funu g\u00f6sterdi. Bu durum, anti-t\u00fcm\u00f6r ba\u011f\u0131\u015f\u0131kl\u0131\u011f\u0131 bask\u0131layarak, hastalar\u0131n tedaviye yan\u0131t\u0131n\u0131n d\u00fc\u015fmesine zemin haz\u0131rlayan bir ortam yaratt\u0131.<\/p>\n
Ara\u015ft\u0131rmada \u00f6ne \u00e7\u0131kan \u00f6nemli bir h\u00fccre grubu, INHBA (\u0130nhibin beta A alt birimi) eksprese eden makrofajlar oldu. Bu INHBA+ makrofajlar, ODSCC\u2019de NODSCC\u2019ye g\u00f6re anlaml\u0131 seviyede \u00e7o\u011falm\u0131\u015f ve en belirgin ba\u011f\u0131\u015f\u0131kl\u0131k bask\u0131lay\u0131c\u0131 imzalar\u0131 ta\u015f\u0131yorlar. Y\u00fcksek imm\u00fcn kontrol molek\u00fclleri, azalm\u0131\u015f MHC (maj\u00f6r histokompatibilite kompleksi) ekspresyonu ve SPP1 gibi t\u00fcm\u00f6r destekleyici belirte\u00e7lerin art\u0131\u015f\u0131, bu h\u00fccrelerin mikro\u00e7evrede \u00f6nc\u00fc rol oynad\u0131\u011f\u0131n\u0131 ortaya koydu. Ayr\u0131ca, ODSCC kaynakl\u0131 INHBA+ makrofajlar, di\u011fer alt tiplerden daha g\u00fc\u00e7l\u00fc imm\u00fcnosupresif fonksiyonlara sahip.<\/p>\n
Makrofajlarla birlikte, ara\u015ft\u0131rmada pro-inflamatuar kanser ili\u015fkili fibroblastlar (iCAF\u2019lar) da ODSCC\u2019nin \u00f6zg\u00fcn t\u00fcm\u00f6r ekolojisinde kritik konumda bulunuyor. Bu iCAF\u2019lar, INHBA genini y\u00fcksek d\u00fczeyde eksprese ederken, ba\u011f\u0131\u015f\u0131kl\u0131k mod\u00fclasyonu ve ekstrasel\u00fcler matriks (ECM) yeniden \u015fekillenmesine ili\u015fkin yollarla zenginle\u015fmi\u015f durumda. TDO2, IDO1 ve DUSP4 genlerinin artm\u0131\u015f d\u00fczeyde ifadesi, \u00f6zellikle triptofan metabolizmas\u0131 ve imm\u00fcn sinyal d\u00fczenlemesi yoluyla imm\u00fcnotolerans yaratmada etkili oluyor. B\u00f6ylece, iCAF\u2019lar hem kimyasal hem de yap\u0131sal ba\u011flamda t\u00fcm\u00f6r\u00fcn ba\u011f\u0131\u015f\u0131kl\u0131k tan\u0131nmas\u0131n\u0131 engelliyor.<\/p>\n
\u00c7al\u0131\u015fman\u0131n en dikkat \u00e7eken bulgular\u0131ndan biri de, betel cevizi i\u00e7eren arekolinin, INHBA ekspresyonunu tetikleyen d\u0131\u015fsal bir fakt\u00f6r olarak tespit edilmesi oldu. \u0130n vitro ortamda THP-1 makrofaj benzeri h\u00fccrelerde arekolin uygulanmas\u0131, INHBA seviyelerinde kayda de\u011fer art\u0131\u015f sa\u011flad\u0131. Bu, ya\u015fam tarz\u0131 fakt\u00f6rlerinin molek\u00fcler d\u00fczeyde t\u00fcm\u00f6r imm\u00fcnosupresyonuna do\u011frudan katk\u0131s\u0131na dair kritik bir ba\u011flant\u0131y\u0131 ortaya koyuyor.<\/p>\n
Mek\u00e2nsal transkriptomik analiz, INHBA+ makrofajlar\u0131n, iCAF\u2019lar\u0131n ve Treg h\u00fccrelerinin t\u00fcm\u00f6r ortam\u0131nda belirli b\u00f6lgelerde birlikte bulunduklar\u0131n\u0131 g\u00f6sterdi. Bu h\u00fccre k\u00fcmelerinin yak\u0131nl\u0131\u011f\u0131, aralar\u0131ndaki parakrin ileti\u015fim ile immunosupresif ni\u015fin \u015fekillendi\u011fine i\u015faret ediyor. Ayr\u0131ca, INHBA\u2019n\u0131n resept\u00f6rleri olan ACVR1, ACVR2A ve ACVR2B ile ili\u015fkili sinyalle\u015fme eksenlerinin, bu h\u00fccre gruplar\u0131nda Treg farkl\u0131la\u015fmas\u0131n\u0131 ve fonksiyonel aktivitesini d\u00fczenledi\u011fi d\u00fc\u015f\u00fcn\u00fcld\u00fc.<\/p>\n
Yap\u0131lan bu kapsaml\u0131 analizler do\u011frultusunda, ODSCC\u2019de INHBA+ makrofajlar ve iCAF\u2019lar\u0131n art\u0131\u015f\u0131, t\u00fcm\u00f6r ba\u011f\u0131\u015f\u0131kl\u0131k bask\u0131lay\u0131c\u0131 mikro\u00e7evresinin (TISME) \u015fiddetli oldu\u011funu g\u00f6steriyor. Bu durum, ba\u011f\u0131\u015f\u0131kl\u0131k kontrol noktas\u0131 engelleyici tedavilere (immune checkpoint blockade) verilen klinik yan\u0131t\u0131n zay\u0131f olmas\u0131n\u0131n molek\u00fcler temelini olu\u015fturmaktad\u0131r.

Ayr\u0131ca INHBA ve ili\u015fkili sinyal yollar\u0131, yeni hedef terapi se\u00e7enekleri i\u00e7in \u00f6nemli bir potansiyele sahip.<\/p>\n
\u00c7ok omikli tek h\u00fccre ve mek\u00e2nsal transkriptomik y\u00f6ntemlerin entegre edilmesi, \u00f6zellikle t\u00fcm\u00f6r i\u00e7i ba\u011f\u0131\u015f\u0131kl\u0131k ve stromal h\u00fccrelerin heterojen yap\u0131s\u0131n\u0131n anla\u015f\u0131lmas\u0131 a\u00e7\u0131s\u0131ndan \u00f6nemli bir ilerleme sa\u011flad\u0131.
