LAMP2 and malignant colon neoplasm: By fusing Her2 affinity to the extracellular N-terminus of human Lamp2, and then using the modified exosomes to co-deliver 5-FU and miR-21 inhibitors (miR-21i), which targets colon cancer cells, effectively reverses the resistance of tumor cells and significantly enhances the toxicity of 5-FU resistant cancer cells [180].
