Abstract
Tumor-draining lymph nodes (TDLNs) are the first sites where tumor components reach and dendritic cells (DCs) present tumor-associated antigens to T cells. DCs rely on autophagy to process tumor antigens into epitope peptides to form epitope-MHC complexes. Selective delivery of autophagy-stimulating drugs to TDLNs may be a precise strategy to boost chemotherapy-induced antitumor immunity. Here, a multistage stimulating strategy is proposed to activate the antitumor immunity cascade by inducing immunogenic death of tumor cells and elevating antigen presentation of DCs in TDLNs. A tumor-microenvironment-responsive "albumin-hitchhiking" micelle is established by self-assembling tumor-targeting oxaliplatin prodrug and lipophilized trehalose prodrug. This demonstrates that lipophilic modification of trehalose with a DSPE tail and the precise exposure in the tumor site enhances its binding to endogenous albumin and realizes TDLNs-selective reflux, where it upregulates antigen processing and presentation of DCs. This study introduces an approach for targeted delivery to TDLNs and provides insights into mechanisms of autophagy in tumor-specific immunity.

Abstract
The ability to maintain a functional proteome by clearing damaged or misfolded proteins is critical for cell survival, and aggregate-prone proteins accumulate in many neurodegenerative diseases, such as Huntington, Alzheimer, and Parkinson diseases. The removal of such proteins is mainly mediated by the ubiquitin-proteasome system and autophagy, and the activity of these systems declines in disease or with age. We recently found that targeting VCP/p97 with compounds like SMER28 enhances macroautophagy/autophagy flux mediated by the increased activity of the PtdIns3K complex I. Additionally, we found that SMER28 binding to VCP stimulates aggregate-prone protein clearance via the ubiquitin-proteasome system. This concurrent action of SMER28 on both degradation pathways resulted in the selective decrease in disease-causing proteins but not their wild-type counterparts. These results reveal a promising mode of VCP activation to counteract the toxicity caused by aggregate-prone proteins.

Abstract
Well-known theories of aging suggest that a certain metabolic defect negatively affects vital activity of the cell, be it oxidative stress, the accumulation of lesions in DNA, the exhaustion of telomeres, or distorted epigenetic processes. The theory of aging considered in the review postulates that an accumulation of progerin on the inner side of the nuclear envelope underlies the above defects. Progerin is a defective precursor of the lamin A nuclear matrix protein in which the C-terminal cysteine, which is removed normally, is retained and modified with a hydrophobic oligoisoprene chain. Progerin molecules attach with their hydrophobic processes to the inner membrane of the nuclear envelope, pushing away the adjacent fibrils of the nuclear matrix and the chromatin periphery. This changes the morphology and shape of the nucleus and alters the properties of the nuclear envelope and pore complexes embedded in it. As progerin accumulates in the nucleus, structural distortions increase in the nucleus, further distorting the nuclear-cytoplasmic transport of macromolecules and leading to the above defects in cell metabolism. This leads to increasing cell death and aging of the body over time. This mechanism of aging has been identified in patients with Hutchinson-Gilford progeria syndrome (HGPS). Mass progerin production in HGPS is caused by the point mutation c.1824C→T in exon 11 of the LMNA gene, which codes for lamins A and C. The mutation stimulates non-standard splicing of the primary transcript during the formation of the lamin A precursor mRNA, thus causing progerin production. Children with progeria who have received the mutation from one of their parents age rapidly and die before 15 years of age. Approaches to progeria treatment are aimed at preventing the formation of progerin or destroying the progerin that has already accumulated. In the latter case, a promising strategy is to use rapamycin or its analogs and other substances and techniques that activate autophagy to purify the cell from progerin. Although in much smaller amounts, progerin is found in progeria-free people and may therefore play a role in natural aging. A maximum age that a person can reach is possible to estimate by taking account of the role that progerin plays in telomere shortening. Encouraging preliminary results achieved in purifying cells from progerin provide a means to develop an optimal procedure for periodic purification of the human body from progerin in order to reduce the rate of aging.

Abstract
Objective: Autophagy influences a wide range of physiological and pathological processes in the human body. In this study, we aimed to investigate the role of autophagy in early-onset preeclampsia (EOPE); autophagy activation by hypoxia could rescue impaired angiogenesis and apoptosis in preeclampsia, leading by ox-LDL. Methods: Transmission electron microscopy was applied to identify autolysosomes in trophoblast cells of the placenta apical region. Quantitative real-time polymerase chain reaction, Western blot, flow cytometry, and wound-healing assays were adopted to determine autophagy activity, angiogenesis, and apoptosis in placenta tissues or HTR8/SVneo cells. Results: Autophagy activity was inhibited in the placenta of women who experienced EOPE; autophagy activation by hypoxia enhanced the migration ability, rescued ox-LDL–mediated impaired angiogenesis in HTR8/SVneo cells [vascular endothelial growth factor A (VEGFA) downregulation and FMS-like tyrosine kinase-1 (FLT1) upregulation], and protected against cell apoptosis (BAX downregulation). Conclusion: Autophagy could maintain the function of trophoblast cells by differentially regulating the expression of VEGFA and FLT1 and protecting against cell apoptosis at the maternal–fetal interface, potentially related to prevention of preeclampsia.

Abstract
Chemoimmunotherapy-induced antitumor immune response is highly dependent on tumor autophagy. When tumor cells are treated with chemoimmunotherapy, timely overactivated autophagy can not only lead more tumor cells to death, but also participate in the endogenous antigen presentation and immune stimulators secretion of dying cells, thus plays a vital role. However, timely and accurately overactivated tumor autophagy during chemoimmunotherapy is of great difficulty. Here, an on-demand autophagy cascade amplification nanoparticle (ASN) is reported to boost oxaliplatin-induced cancer immunotherapy. ASN is prepared by self-assemble of autophagy-responsible C-TFG micelle and is followed by electrostatic binding of oxaliplatin prodrug (HA-OXA). After entering tumor cells, the HA-OXA shell of ASN first responds to the reduction microenvironment and releases oxaliplatin to trigger tumor immunogenic cell death and mildly stimulates tumor autophagy. Then, the exposed C-TFG micelle can sensitively respond to oxaliplatin-induced autophagy and release a powerful autophagy inducer STF-62247, which precisely transforms autophagy to "overactivated" condition, leading tumor cells to autophagic death and enhance subsequent tumor antigen processing of the dying cells. In CT26 tumor-bearing mice, ASN exhibits optimal immune stimulation and antitumor efficiency due to its on-demand autophagy induction ability.

Abstract
Autophagy is a multistep catabolic process through which misfolded, aggregated or mutated proteins and damaged organelles are internalized in membrane vesicles called autophagosomes and ultimately fused to lysosomes for degradation of sequestered components. The multistep nature of the process offers multiple regulation points prone to be deregulated and cause different human diseases but also offers multiple targetable points for designing therapeutic strategies. Cancer cells have evolved to use autophagy as an adaptive mechanism to survive under extremely stressful conditions within the tumor microenvironment, but also to increase invasiveness and resistance to anticancer drugs such as chemotherapy. This review collects clinical evidence of autophagy deregulation during cholangiocarcinogenesis together with preclinical reports evaluating compounds that modulate autophagy to induce cholangiocarcinoma (CCA) cell death. Altogether, experimental data suggest an impairment of autophagy during initial steps of CCA development and increased expression of autophagy markers on established tumors and in invasive phenotypes. Preclinical efficacy of autophagy modulators promoting CCA cell death, reducing invasiveness capacity and resensitizing CCA cells to chemotherapy open novel therapeutic avenues to design more specific and efficient strategies to treat this aggressive cancer.

Abstract
BACKGROUND It is well accepted that both rosuvastatin and resveratrol exert neuroprotective effects on cerebral ischemia/reperfusion injury through some common pathways. Resveratrol has also been demonstrated to protect against cerebral ischemia/reperfusion injury through enhancing autophagy. Thus, we hypothesized that combined rosuvastatin and resveratrol pretreatment had synergistic effects on cerebral ischemia/reperfusion injury. MATERIALS AND METHODS Adult male Sprague Dawley rats receiving middle cerebral artery occlusion surgery as animal model of cerebral ischemia/reperfusion injury were randomly assigned to 4 groups: control, resveratrol alone pretreatment, rosuvastatin alone pretreatment, and combined rosuvastatin and resveratrol pretreatment. Rosuvastatin (10 mg/kg) or resveratrol (50 mg/kg) was administrated once a day for 7 days before cerebral ischemia onset. RESULTS We found that combined rosuvastatin and resveratrol pretreatment not only significantly decreased the neurologic defective score, cerebral infarct volume, the levels of caspase-3, and Interleukin-1β (IL-1β) but also significantly increased the ratios of Bcl-2/Bax and LC3II/LC3I, as well as the level of Becline-1, compared with resveratrol alone or rosuvastatin alone pretreatment group. Rosuvastatin alone pretreatment significantly increased the ratio of LC3II/LC3I and the level of Beclin-1. However, there were no significant differences in the neurologic defective score, cerebral infarct volume, the levels of caspase-3, IL-1β, and Beclin-1, and the ratios of Bcl-2/Bax and LC3II/LC3I between resveratrol pretreatment group and rosuvastatin pretreatment group. CONCLUSIONS Synergistically enhanced antiapoptosis, anti-inflammation, and autophagy activation might be responsible for the synergistic neuroprotective effects of combining rosuvastatin with resveratrol on cerebral ischemia/reperfusion injury.
