一般描述
Tn 抗原是一种截短的 O -聚糖，在结直肠癌（CRC）中常见。通常在癌细胞中高水平表达。Tn 抗原体积小，结构简单。其在人体内具有非生理性聚糖结构，因此可能被免疫系统识别为异物。
生化/生理作用
Tn 抗原通过 H-Ras 介导的上皮间质转换刺激结直肠癌转移。作为几种重要复合物 O -聚糖的前体。携带 Tn 抗原的所有谱系中的血细胞亚群导致一种称为 Tn 综合征的血液疾病。
包装

Glioblastoma is the most aggressive brain malignancy, for which immunotherapy has failed to prolong survival. Glioblastoma-associated immune infiltrates are dominated by tumor-associated macrophages and microglia (TAMs), which are key mediators of immune suppression and resistance to immunotherapy.

Tn antigen is a tumor-associated antigen that appears on cancer cells as a result of aberrant O-glycosylation. The most studied form of Tn antigen is found in mucins, in particular, in mucin 1 (MUC1). Antibodies against this form of Tn

Aberrant O-glycosylation truncates O-glycans and is known to be closely associated with colorectal cancer (CRC), a major gastrointestinal tumor. CD44 is one of the highly post-transcriptionally modified O-glycoproteins participating in a series of physiological and pathobiological processes. In this research

Core 1- and 3-derived mucin-type O-glycans are primary components of the mucus layer in the colon. Reduced mucus thickness and impaired O-glycosylation are observed in human ulcerative colitis. However, how both types of O-glycans maintain mucus barrier function in the
