Monoclonal Antibodies Protect Aged Rhesus Macaques From SARS-CoV-2-Induced Immune Activation and Neuroinflammation
Verma et al., Cell Reports. 2021.

In aged diabetic female rhesus macaques, prophylactic administration of neutralizing monoclonal antibodies (mAbs) effectively limits SARS-CoV-2 replication in both the upper and lower respiratory tract, and decreases immune activation, including reducing interferon-induced chemokines and limiting effector CD4 T cell influx into the cerebrospinal fluid. These protective mechanisms took place in the areas of the body targeted by the virus and may prevent adverse inflammatory consequences of SARS-CoV-2 infection in high-risk populations.

Innate Immunity Stimulation via CpG Oligodeoxynucleotides Ameliorates Alzheimer’s Disease Pathology in Aged Squirrel Monkeys
Patel et al., Brain: A Journal of Neurology. 2021.

Alzheimer's disease is the only illness among the top 10 causes of death for which there is no disease-modifying therapy. The authors have shown in transgenic Alzheimer's disease mouse models that harnessing innate immunity via TLR9 agonist CpG oligodeoxynucleotides (ODNs) modulates age-related defects associated with immune cells and safely reduces amyloid plaques, oligomeric amyloid-β, tau pathology, and cerebral amyloid angiopathy (CAA). They used a nonhuman primate model for sporadic Alzheimer's disease pathology that develops extensive CAA-elderly squirrel monkeys. They demonstrate that long-term use of Class B CpG ODN 2006 induces a favorable degree of innate immunity stimulation. CpG ODN 2006 has been well established in numerous human trials for a variety of diseases. This evidence together with their earlier research validates the beneficial therapeutic outcomes and safety of this innovative immunomodulatory approach.
