检测原理
试剂盒采用双抗体一步夹心法酶联免疫吸附试验(ELISA)。往预先包被颗粒酶B(Gzms-B)抗体的包被微孔中,依次加入标本、标准品、HRP标记的检测抗体,经过温育并 洗涤。用底物TMB显色,TMB在过氧化物酶的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。颜色的深浅和样品中的颗粒酶B(Gzms-B)呈正相关。用酶标仪在450nm 波长下测定吸光度(OD 值),计算样品浓度。
be a consequence of an increased glycolytic metabolism in autophagy-de?cient T cells and to changes in the landscape of histone methylation that a?ected genes involved in the regulation of T cell activation and metabolism (DeVorkin et al., 2019 ). A second study showed that elevated potassium levels in the tumor microenvironment resulted in reduced nutrient uptake by CD8+ T cells and the consequent activation of autophagy, which caused metabolic reprograming toward mitochondrial OXPHOS. Increased OXPHOS forced the preferential
autophagy in the maintenance of stem properties in other cell types (Garcia-Prat et al., 2016 ). Although both studies point toward the ability of autophagy to reprogram CD8+ T cell metabolism, alter epigenetic marks and limit e?ector functions, they provide di?erent functional consequences in terms of tumor control resulting from the activation of autophagy in T cells. Though the reason for this discrepancy may reside in the di?erent functional outcomes that may be caused by long-term (knock-out model) or acute loss of autophagy, both studies support, nevertheless, a central role of autophagy in the modulation of anti-tumor CD8+ T cell responses.
