- | Although early stage autoimmune disease often succumbs to antibiotic therapy, antibiotics appear to lose utility as disease progresses. Recent sequencing of microbial DNA has confirmed that some pathogens ensure their persistence by reducing expression of, and transcription by, the VDR nuclear receptor, which is at the heart of the human innate immune system. | + | Although early stage autoimmune disease often succumbs to antibiotic therapy, antibiotics appear to lose utility as disease progresses.
