Little is known about autophagy during HIV infection. Recently, two different teams reported important dysfunctions of autophagy in HIV-infected patients despite sustained suppressive antiretroviral therapy. As altered autophagy is strongly linked to cellular senescence and chronic inflammation, two hallmarks of HIV-infected patients despite long-term suppressive antiretroviral therapy, it is important to improve our knowledge in the area. Our main objective is to determine whether all or part of mononuclear cell subpopulations (CD4+ and CD8+ T lymphocytes, and monocytes) exhibit a defect in autophagy function in a cohort of HIV-infected patients who are virologically-controlled (plasma HIV RNA \<50 copies / ml) either spontaneously (i.e. HIV controllers or post-treatment controllers) or after they started antiretroviral therapy at different time points (i.e. at the acute or chronic phases), as compared with a control group (i.e. uninfected healthy blood donors).
NCT05953350
In order to explore the safety and antitumor efficacy of different doses of CDK4/6 inhibitor Palbociclib in combination with the autophagy inhibitor hydroxychloroquine (HCQ) , a phase Ib/II study was conducted. This study will adopt a 3+3 design and include three predefined dose groups of palbociclib: 100mg QD, 150mg QD, and 200mg QD. Initially, 600mg bid dose of hydroxychloroquine group will be administered in combination. The trial will use the first cycle (28 days) as the observation period for tolerability, observing and evaluating the occurrence of DLTs after medication and determining the maximum tolerated dose/maximum administered dose (MTD/MAD) and recommended phase 2 dose (RP2D) of the combination therapy. This study improves the efficacy of CDK4/6 inhibitors in the treatment of solid tumors by reversing DTP status through the use of HCQ.
NCT04842864
Autophagy, which involves the degradation of aged or damaged cellular components, has been shown to extend healthspan and lifespan in multiple organisms, including flies, worms, and mice. Research has also demonstrated that autophagy declines with age in these simpler experimental models. However, human studies are lacking. Our study seeks to determine whether fasting, a robust stimulus of autophagy, upregulates autophagy in humans, and whether autophagy is reduced in healthy older people compared to healthy younger individuals.
NCT02678325
The objective of this study is to compare the difference in daily protein intake of critically ill patients in two standardized enteral nutrition formulas (20% versus 33% percent) with the same caloric density of 1.2 kcal/ml. The total amount of protein taken in on day four after starting the early enteral feeding is defined as primary endpoint.
NCT03267160
This research will be the first study for exosomes purified in blood and urine from septic patients who had multiple organ failures. Proteomics studies in exosomes from blood or urine specimens. Analyze autophage, and apoptosis related biomarkers of exosomes by bioinformatics. To find the correlations between exosomes biomarkers and hemodynamic parameters.

The exact mechanism of impairment of autophagy in vitiligo has not yet been determined.
