Immunopharmacology Comments
OGG1 has recognised roles in processes that are associated with innate and adaptive immunity [1-2], particulary as an initiator of proinflammtory responses [1]. At least some of OGG1's actions in the immune system and inflammation are related to its ability to recruit site-specific transcription factors and modulate the expression of genes that are involved in the producation of chemokines/cytokines and the activation/recruitment of inflammatory cells, in order to mount an effective innate immune response. As a result, pharmacological OGG1 inhibition is being explored as a novel antiinflammatory mechanism.

General Comments
The OGG1 enzyme is responsible for the excision of 8-oxoguanine from oxidatively-damaged DNA. It is located intracellularly to mitochondria. OGG1 has also been identified as a transcription modulator, that can regulate transcription factor homing, recruit chromatin remodelers and induce downstream signaling cascades that alter gene expression.
