WebAug 9, 1999 · Thus, EGFP could be used as a selectable marker to enrich gene-modified tumor cells used for immunization purposes without interfering with antitumor responses. WebThe monitoring of a fluorescent-labelled autophagy marker, eGFP-CgAtg8, revealed a high autophagy activity in the hyphae surrounding the acervuli.

WebApr 5, 2024 · To probe this notion, we monitored autophagy flux using the EGFP-RFP-LC3 reporter system [38,39]. As shown in Figure 5 D, the Rapamycin control increased both yellow (autophagosomes) and red (autolysosomes) signals, indicating that the rapamycin control induces the complete autophagic process. WebAutophagy is an important process by which pathogens and damaged or unused organelles are eliminated. The role of autophagy in development and the immune response to pathogens is well established.
