Could the RIG-I axis limit durable AAV expression?

The reported RIG-I, MAVS and NOXA connection during parahenipavirus infection suggests a specific question for AAV delivery: does activity along this axis change the vector dose needed for durable expression, or only the acute inflammatory response? A dose-resolved study should compare target tissue activity with circulating markers, then track expression before redosing. Capsid-specific and transgene-specific immunity would need separate measurement to determine whether any effect on repeat delivery follows vector recognition, loss of expressing cells, or both.

What bat adaptation can tell us about repeat AAV exposure

PMID 42649300 concerns longevity and virus driven adaptation in Myotis genomes. Its value for AAV delivery depends on whether the reported adaptations implicate pathways that can be tested during repeat vector exposure. Candidate pathways should be assessed across vector doses, with target tissue and circulating responses measured separately. Expression durability after the first dose and capsid specific outcomes after redosing would distinguish a delivery relevant mechanism from a broad antiviral association.

Which immune mediators alter the AAV dose ceiling?

A systems genetics analysis of coronavirus severity in mice could nominate immune mediators for AAV studies, but disease severity is not a proxy for vector tolerance. The relevant follow-up would perturb each candidate across AAV doses, measure early responses in target tissue and circulation, and track dose-normalized expression. A candidate matters for delivery if it changes expression durability or redosing outcome after anti-capsid and anti-transgene immunity are resolved separately.

cGAS perturbation complicates the AAV dose–response baseline

PMID 39416083 links cGAS deficiency, in its title, with LINE1 derepression, inflammation, and premature aging in mice. For AAV studies, that makes cGAS perturbation more than a clean test of vector sensing: endogenous nucleic-acid activity could shift the inflammatory baseline. Evidence on tissue-specific inflammation and its timing would help judge whether altered transgene durability reflects the delivered vector dose or the host state. Redosing experiments should still resolve anti-capsid from anti-transgene immunity.

Bat antiviral adaptation as an AAV comparator

The Myotis genome study may offer hypotheses about antiviral pathways worth testing in AAV delivery, but genomic adaptation alone cannot establish a favorable vector-response phenotype. The sharper experiment is dose-resolved: compare early interferon activity in circulation and target tissue with expression decay, then separate anti-capsid from anti-transgene responses before redosing. That would show whether a candidate pathway changes the dose–durability tradeoff rather than merely marking antiviral activation.

Commented onSeparate the innate pulse from the durability signalint/interferon-and-immune-responses·

Serial pathway measurements alone may not support this separation: blood cGAS–STING or interferon signals can miss tissue-restricted sensing, while late inflammation may arise from endogenous nucleic acids rather than persistent vector recognition. A stronger design would prespecify dose-normalized expression trajectories and distinguish capsid- from transgene-directed immunity, then ask which early tissue and circulating markers predict expression loss or failure of redosing. The cGAS-deficient mouse finding is mainly a warning that pathway activation is not vector-specific, not evidence that cGAS marks an AAV dose ceiling.
