<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">新陈代谢广泛参与病理和生理过程,如生长、<span style="color: black;">生长</span>和衰老,并受到生物体的精细调节。一旦新陈代谢失调,就会<span style="color: black;">显现</span>痛风、心血管<span style="color: black;">疾患</span>等严重疾病。代谢重编程是癌症的一个<span style="color: black;">重要</span>标志,它赋予肿瘤对<span style="color: black;">连续</span>代谢应激的适应能力,从而促进癌症<span style="color: black;">发展</span>。癌细胞<span style="color: black;">能够</span><span style="color: black;">经过</span>降低肿瘤浸润免疫细胞的代谢适应性来<span style="color: black;">控制</span>抗肿瘤免疫。<span style="color: black;">另外</span>,改变的代谢物<span style="color: black;">能够</span>将信息传递到细胞核中并重塑表观遗传景观。例如,几种代谢物,如蛋氨酸、乙酰辅酶A和乳酸,是调节肿瘤<span style="color: black;">关联</span>基因表达的表观遗传修饰的<span style="color: black;">源自</span>。靶向肿瘤和免疫细胞代谢,例如<span style="color: black;">经过</span>谷氨酰胺酶和葡萄糖摄取<span style="color: black;">控制</span>剂,是一个新兴的癌症治疗<span style="color: black;">行业</span>。<strong style="color: blue;">然而,迫切<span style="color: black;">必须</span>更理想、更精确的代谢靶点。阐明<span style="color: black;">反常</span>代谢特征<span style="color: black;">针对</span><span style="color: black;">认识</span>肿瘤发展机制和<span style="color: black;">研发</span>新型靶向疗法至关<span style="color: black;">要紧</span>。</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">免疫逃逸是癌症的另一个标志,它<span style="color: black;">准许</span>癌细胞<span style="color: black;">经过</span>募集<span style="color: black;">控制</span>性免疫细胞和改变肿瘤微环境(TME)来逃避人体免疫系统的检测和攻击。越来越多证据<span style="color: black;">显示</span>,TME中的代谢重编程是肿瘤免疫逃逸的<span style="color: black;">重要</span>驱动<span style="color: black;">原因</span>,它改变了免疫细胞的活化、分化和杀伤。TME中的几种代谢物,如乳酸、钾、衣康酸和L-精氨酸,会损害肿瘤浸润淋巴细胞(TILs)的功能,并支持调节性T(Treg)细胞的能量供应,以促进免疫逃逸。<strong style="color: blue;"><span style="color: black;">因此呢</span>,探索驱动免疫逃逸的<span style="color: black;">重要</span>代谢物<span style="color: black;">针对</span>理解免疫逃逸机制和靶点识别至关<span style="color: black;">要紧</span>。</strong>靶向代谢脆性<span style="color: black;">能够</span>重塑抗肿瘤TME,<span style="color: black;">加强</span>免疫<span style="color: black;">检测</span>点<span style="color: black;">控制</span>剂的效率。</p>
