MAP1LC3A and infection: Overexpression of LC3 in primary GECs through transfection of Green-Fluorescent-Protein (GFP)-LC3 also showed a high colocalization rate with P. gingivalis (∼99%) at 24 hours infection (Fig. 4B) which is was also supported by immunofluorescence staining of endogenous LC3 (Fig. 4C).
