HHV-7 and Natural Killer Cells
The Human Herpesvirus-7 (HHV-7) U21 Immunoevasin Subverts NK-Mediated Cytoxicity through Modulation of MICA and MICB
Christine L. Schneider and Amy W. Hudson
Abstract
Herpesviruses have evolved numerous immune evasion strategies to facilitate establishment of lifelong persistent infections. Many herpesviruses encode gene products devoted to preventing viral antigen presentation as a means of escaping detection by cytotoxic T lymphocytes. The human herpesvirus-7 (HHV-7) U21 gene product, for example, is an immunoevasin that binds to class I major histocompatibility complex molecules and redirects them to the lysosomal compartment. Virus infection can also induce the upregulation of surface ligands that activate NK cells. Accordingly, the herpesviruses have evolved a diverse array of mechanisms to prevent NK cell engagement of NK-activating ligands on virus-infected cells. Here we demonstrate that the HHV-7 U21 gene product interferes with NK recognition. U21 can bind to the NK activating ligand ULBP1 and reroute it to the lysosomal compartment. In addition, U21 downregulates the surface expression of the NK activating ligands MICA and MICB, resulting in a reduction in NK-mediated cytotoxicity. These results suggest that this single viral protein may interfere both with CTL-mediated recognition through the downregulation of class I MHC molecules as well as NK-mediated recognition through downregulation of NK activating ligands.

This is what oral Kaposi's Sarcoma looks like. Source:  https://doctorspiller.com/kaposis-sarcoma/ Compare it to these crimson crescent lesions in the mouths of Chronic Fatigue Syndrome patients. "Burke A. Cunha, MD, discovered what he called crimson crescents in the mouths of 80% of his CFS patients. After the word got out, Cunha received calls from other parts of the country. Physicians began telling him that they also were finding the crimson crescents in their patients once they looked for them." https://www.prohealth.com/library/crimson-crescents-facilitate-chronic-fatigue-syndrome-cfs-diagnosis-11266 Chronic Fatigue Syndrome patients may have undiagnosed internal Kaposi's Sarcoma.

Why is the Chronic Fatigue Syndrome community ignoring the biggest breakthrough?

From the University of Wurzburg: "While HHV-6 was long believed to have no negative impact on human health, scientists today increasingly suspect the virus of causing various diseases such as multiple sclerosis or chronic fatigue syndrome. Recent studies even suggest that HHV-6 might play a role in the pathogenesis of several diseases of the central nervous system such as schizophrenia, bipolar disorder, depression or Alzheimer's." https://www.uni-wuerzburg.de/en/news-and-events/news/detail/news/viruses-under-the-microscope/ The scientist who deserves a Nobel Prize for his work on HHV-6 and Chronic Fatigue Syndrome. https://www.uni-wuerzburg.de/en/news-and-events/news/detail/news/viruses-under-the-microscope/ Viruses Under the Microscope 09/14/2018 Human herpesviruses such as HHV-6 can remain dormant in cells for many years without being noticed.

Nadler did that at the urging of Charles Ortleb, the publisher and the New York Native and his reporter Neenyah Ostrom. Ortleb and Ostrom had made the case to Nadler that Chronic Fatigue Syndrome and the virus it had been linked to, HHV-6, were serious public health issues.                                                 In an interview in New York Native with Neenyah Ostrom,Congressman Nadler said, "Congress can mandate research into CFS as a viral disease.
