    TLDR Low-level laser therapy may help uninfected cells but has different effects on coronavirus-infected cells.
    This study investigates the effect of low-level laser therapy (LLLT) on SARS-CoV-2-infected HEK293/ACE2 cells. Using various biological assays, the researchers found that both infected non-irradiated and irradiated cells showed signs of cell stress and produced reactive oxygen species (ROS). However, there were more dead cells in the infected group, while the uninfected irradiated cells had more viable cells. The findings suggest that LLLT may have potential therapeutic effects in the context of SARS-CoV-2 research.
