In addition, BNIP3-mediated mitophagy played a protective role against VSMC calcification in the presence of lactate. This study suggests that lactate accelerates osteoblastic phenotype transition of VSMC and calcium deposition partly through the BNIP3-mediated mitophagy deficiency induced oxidative stress and apoptosis.

Blocking endolysosomal pathways using autophagy inhibitors prevented the degradation of AANTs through lysosomes. Our results add new insights into the pathways and mechanisms of intracellular trafficking of AANTs, and suggest that intracellular trafficking and lysosomal degradation are highly interdependent and important for efficient drug delivery, and should be evaluated together for drug carrier development.

[VIRTUAL] Homozygous mutations of ARFGAP1 gene in severe sarcoidosis (Pre-congress content) - Jul 15, 2020 - Abstract #ERS2020ERS_3737; RAC1 is one of the main targets of azathioprine (AZA), an immunosuppressive drug used in corticosteroid (CS) refractory sarcoidosis...We would hypothesize that ARFGAP1 mutated isoforms have lost their inhibitory function with a consequence of hyperactivation of RAC1 thus leading to autophagy inhibition. Autophagy disruption seems to be an interesting element of pathophysiology in sarcoidosis, previously evoked in WES studies and through the efficacy of autophagy modulating drug during sarcoidosis.

[VIRTUAL] Cigarette-decreased NAD/SIRT1 aggravates pulmonary fibrosis by promoting senescence of alveolar type 2 cells through autophagy inhibition and mitochondrial oxidative stress induction (Pre-congress content) - Jul 15, 2020 - Abstract #ERS2020ERS_223; After senescent markers were increased, they were treated with bleomycin (BLM) and smoke for 4 weeks...Then, effects of autophagy inducer rapamycin, SIRT1 activator SRT1720, NAD+ precursor NMN, PARP1 inhibitor olaparib and mitochondrial ROS (mtROS) scavenger, mitoquinone (MQ) were examined...Conclusion Cigarette-decreased NAD+/SIRT1 resulting from PARP1 activation induce AT2 senescence by inhibiting autophagy, which further activate PARP1 via mtROS-induced DNA damage by impairing mitophagy. Therefore, there is a positive loop in cigarette-induced senescence, which may play a key role in lung fibrosis.

Intact autophagy is necessary for endothelial cells to invade the extracellular matrix as well as for the expression of active endothelial MMP14.

Sirolimus is an agent for the treatment of LAM, indicated for FEV1 of less than 70% of predicted, patients on traditional therapies are recommended to be transitioned to newer FDA approved drugs for LAM.

[VIRTUAL] The Influence of Autophagy Inhibition on Sepsis-Induced Skeletal Muscle Wasting, Metabolic Derangements and Mortality (ATS 2020 Virtual) - Jul 6, 2020 - Abstract #ATSI2020ATS-I_3747; We conclude that autophagy plays a protective role by preserving muscle mitochondrial quality and function and that autophagy inhibition in skeletal muscles worsens sepsis-induced loss of body weight and muscle atrophy possibly due to exaggerated responses to catabolic stimuli triggered by sepsis. Our results also indicate that autophagy in septic skeletal muscles play a protective role against sepsis-induced metabolic derangements and mortality.

Journal: Autophagy Inhibition Sensitizes Renal Tubular Epithelial Cell to G1 Arrest Induced by Transforming Growth Factor beta (TGF-β). (Pubmed Central) - Jun 23, 2020 Human kidney-2 (HK-2) cells were stimulated by TGF-ß with or without a combined treatment of autophagy inhibitor chloroquine (CQ) or bafilomycin A1 (Baf)...Western blot analysis showed that TGF-ß-induced expression of extracellular matrix fibronectin was notably upregulated in the presence of autophagy inhibitors. CONCLUSIONS Inhibition of autophagy sensitizes the TECs to G1 arrest and proliferation suppression induced by TGF-ß that contributes to the induction of tubulointerstitial fibrosis.

In this short perspective, we discuss the roles of CQ/HCQ in the treatment of COVID-19 patients and propose new ways of possible treatment for SARS-CoV-2 infection based on the molecules that selectivity target autophagy.
