Abstract

The lysosomal degradation pathway of autophagy has a crucial role in defence against infection, neurodegenerative disorders, cancer and ageing. Accordingly, agents that induce autophagy may have broad therapeutic applications. One approach to developing such agents is to exploit autophagy manipulation strategies used by microbial virulence factors. Here we show that a peptide, Tat-beclin 1-derived from a region of the autophagy protein, beclin 1, which binds human immunodeficiency virus (HIV)-1 Nef-is a potent inducer of autophagy, and interacts with a newly identified negative regulator of autophagy, GAPR-1 (also called GLIPR2). Tat-beclin 1 decreases the accumulation of polyglutamine expansion protein aggregates and the replication of several pathogens (including HIV-1) in vitro, and reduces mortality in mice infected with chikungunya or West Nile virus. Thus, through the characterization of a domain of beclin 1 that interacts with HIV-1 Nef, we have developed an autophagy-inducing peptide that has potential efficacy in the treatment of human diseases.

  • MTOR-independent methods for stimulating autophagy include direct stimulation of AKT and BECN1, activating MAPK8/JNK1 to dissociate BCL2 from BECN1, applying Tat-Beclin 1, SIRT1-associated starvation, and disrupting nonsense-mediated RNA decay.

    “The array of MTOR-independent methods for stimulating autophagy also includes direct stimulation of AKT and BECN1, activating MAPK8/JNK1 to dissociate BCL2 from (and thereby disinhibit) BECN1, applying the synthetic peptide Tat-Beclin 1, SIRT1-associated starvation, and disrupting nonsense-mediated RNA decay [513–517] (Figure 3).”
  • mTOR-independent autophagy-inducing agents include activators of AMPK and SIRT1, chemicals that reduce intracellular inositol or IP3 levels (lithium, carbamazepine, sodium valproate), K+-ATP channel opener minoxidil and Tat-beclin 1 peptide.

    “mTOR-independent autophagy-inducing agents include activators of AMPK29 and SIRT136, chemicals that reduce intracellular inositol or IP3 levels (such as lithium, carbamazepine and sodium valproate), the K+-ATP channel opener minoxidil and the Tat–beclin 1 peptide, among others193-195.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
