암세포 표면의 이상 당화(糖化, glycosylation) 패턴이 항암 약물 전달의 새로운 표적으로 떠오르고 있다. 나노캐리어와 당화 항체를 이용해 암세포를 정밀 공격하면서 다제내성을 극복하는 기술이 주목받고 있다는 리뷰 논문이 발표됐다.
*Current Drug Delivery*에 게재된 이번 리뷰는 암세포의 이상 당화 패턴이 종양 진행, 전이, 면역 회피, 약물 내성에 관여하는 기전을 분석하고, 이를 치료에 역이용하는 최신 약물 전달 시스템을 종합했다.
당화된 나노캐리어는 암세포 표면에 과발현된 수용체와 결합하는 당 리간드를 활용해 종양 세포를 선택적으로 표적화하면서 정상 조직의 독성을 최소화할 수 있다. 당화 나노캐리어·항체·융합 단백질은 약물 안정성, 세포 흡수율, 면역 조절 효과를 높여 항암 치료 효능을 향상시키는 것으로 나타났다.
2020~2025년 사이 유럽·구글 특허·Lens.org 데이터베이스의 특허 동향은 비소세포폐암, 유방암, 전립선암에서 다제내성을 극복하기 위한 당화 기반 표적 전달 기술에 집중돼 있다. 리뷰는 세포 흡수 기전, 종양 전이 억제, 면역 회피 차단, 페롭토시스 유도, 세포 노화 조절 등 다양한 응용 가능성도 제시했다.
연구팀은 당화 기반 진단·치료가 개인 맞춤 의학으로 발전하고 있다고 강조했다.

Cancer cells carry distinctive molecular signatures on their surfaces — and among the most exploitable are their abnormal glycosylation patterns. A comprehensive review published in *Current Drug Delivery* surveys how scientists are using these aberrant sugar-protein modifications to engineer drug delivery systems that attack tumors with precision while bypassing healthy tissue.
Glycosylation — the enzymatic attachment of carbohydrate chains to proteins and lipids — is dysregulated in virtually all solid tumors. These abnormal patterns promote tumor growth, immune evasion, metastasis, and drug resistance. But they also present a unique therapeutic opportunity: cancer-associated glycans serve as specific binding targets that can be exploited by glycosylated drug carriers.
Glycosylated nanocarriers coated with tumor-targeting sugar ligands can selectively bind to overexpressed receptors on cancer cell surfaces, triggering receptor-mediated endocytosis that delivers drug payloads directly inside tumor cells. Compared with conventional chemotherapy, this approach dramatically improves cellular drug uptake while reducing systemic toxicity. Glycosylated antibodies and fusion proteins have shown similarly favorable profiles, enhancing drug stability and modulating immune responses against tumors.
Patent analysis from European databases, Google Patents, and Lens.org (2020–2025) reveals intense innovation targeting multidrug resistance in non-small cell lung cancer, breast cancer, and prostate cancer. Emerging applications include glycosylation strategies that simultaneously target ferroptosis induction, cellular senescence, metabolic reprogramming, and immune checkpoint pathways.
The review positions glycosylation-based drug delivery as a cornerstone technology for personalized oncology — where treatments can be matched to individual tumor glycan profiles — while identifying manufacturing consistency and immunogenicity as key challenges remaining before widespread clinical adoption.
> Health tip: If you or a loved one is undergoing cancer treatment, discuss with your oncologist whether molecularly targeted therapies or clinical trials investigating novel delivery approaches are appropriate — personalized cancer medicine is advancing rapidly.
