Abstract

Macrophages play a critical role in lung injury and repair processes. Their functions can be broadly classified into two polarized phenotypes. The M1 macrophages promote inflammation and defense against pathogens, while the M2 macrophages are involved in tissue repair and resolution of inflammation.Gene manipulation techniques can be used to modulate macrophage polarization during lung injury. 1. Transcription factors: Transcription factors are proteins that regulate gene expression. Manipulating the expression or activity of specific transcription factors can influence macrophage polarization. 2. Cytokines and chemokines: Cytokines and chemokines are small signaling molecules that mediate immune responses. They can be used to manipulate macrophage polarization by inducing the expression of specific cytokines. 3. MicroRNAs (miRNAs): miRNAs are small non-coding RNA molecules that regulate gene expression at the post-transcriptional level. Certain miRNAs have been identified as regulators of macrophage polarization. 4. Genetic engineering: Genetic engineering techniques, such as CRISPR-Cas9, can be used to directly modify genes involved in macrophage polarization. By introducing specific genetic modifications, researchers can enhance or suppress the expression of genes associated with M1 or M2 polarization.Manipulating macrophage polarization through gene manipulation techniques holds promise for modulating immune responses and promoting lung repair during injury.
