Intra-monocyte pathogens delineate autism subgroups
1Institute for Molecular Introspections, Estes Park, Colorado, USA. aspergerian@yahoo.com
Abstract:
Immune panels of many autism-spectrum children reveal signs of atypical infections and shifted cell counts. In conjunction with trait-related cerebral hypometabolism and hypoperfusion, these findings suggest a hypothesis: Several autism-spectrum subgroups derive from intra-monocyte pathogens such as measles virus, cytomegalovirus, human herpesvirus 6, and Yersinia enterocolitica. Furthermore, with much inter-child variation, their effects manifest as diminished hematopoiesis, impaired peripheral immunity, and altered blood-brain barrier function often accompanied by demyelination. In some such children, one or more of these pathogens persists as a chronic-active, seemingly subclinical infection etiologically significant to the child's autistic traits. Within these subgroups, immune impairments and atypical infections may be treatable.
Insights
Certain autism spectrum subgroups may stem from infections within monocytes, like measles virus or cytomegalovirus. These infections can impact immunity and brain function, potentially offering treatment avenues for some children.
Area of Science:
- Neuroimmunology
- Infectious Disease
- Developmental Neuroscience
Background:
- Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with diverse etiologies.
- Immune dysregulation and atypical infections are frequently observed in individuals with ASD.
- Cerebral hypometabolism and hypoperfusion are associated with autistic traits.
Purpose of the Study:
- To propose a hypothesis linking specific intra-monocyte pathogens to subgroups of autism spectrum disorder.
- To explore the immunological and neurological consequences of these potential infections in ASD.
- To identify potential therapeutic targets for affected subgroups.
Main Methods:
- Review of immune panels from children with autism spectrum disorder.
- Analysis of findings related to cerebral metabolism and perfusion.
- Hypothesizing etiological links between specific pathogens and ASD traits.
Main Results:
- Observed atypical infections and altered cell counts in ASD immune panels.
- Hypothesized that pathogens like measles virus, cytomegalovirus, HHV-6, and Yersinia enterocolitica may underlie certain ASD subgroups.
- Noted effects including diminished hematopoiesis, impaired immunity, altered blood-brain barrier function, and demyelination.
- Identified persistent, subclinical infections in some children with ASD.
Conclusions:
- Specific intra-monocyte pathogens may be etiologically significant in subgroups of autism spectrum disorder.
- Immune impairments and atypical infections observed in these subgroups may be treatable.
- Further research into pathogen-specific treatments for ASD subgroups is warranted.
