How can an innate immune sensor shape viral evolution? In recent work, Takata et al. (2017) determined that the antiviral protein ZAP recognizes CG dinucleotide composition to differentiate self from non-self. This pressure may have driven CG dinucleotide suppression in HIV-1 and other RNA viruses to evade host antiviral defenses.

Immune dysfunction in autism spectrum disorder (ASD) has been widely reported and is associated with increased impairments in social interactions, communication, repetitive behaviors, anxiety and gastrointestinal problems. Several lines of evidence point towards increased activation of the innate immune system including activation of microglia, increases in innate inflammatory cytokines/chemokines in blood, brain tissue and CSF, activated dendritic cells and macrophages, and abnormal peripheral monocyte cell function. Monocytes are major players in innate immunity and have important functions in the phagocytosis of pathogens or debris, immune defense and cytokine/chemokine production.

Background: Parkinson's disease (PD) is characterised by degeneration of ventral midbrain dopaminergic (DA) neurons and abnormal deposition of α-synuclein (α-syn) in neurons. Activation of the innate immune pathogen recognition receptor toll-like receptor 2 (TLR2) is associated with exacerbation of α-syn pathology. TLR2 is increased on neurons in the PD brain, and its activation results in the accumulation and propagation of α-syn through autophagy inhibition in neurons.

Background: Fibromyalgia is a complex condition that has long puzzled the medical community. Hypotheses to explain the chronic widespread pain associated with the disease have evolved significantly over the years. However, research efforts to identify disease-specific biomarkers and develop effective treatments have been largely unsuccessful.
