Autophagy is a highly conserved, tightly regulated cellular process that degrades intracellular constituents via lysosomes. Autophagy mediates many normal cellular functions and is dysregulated in numerous diseases. This Thematic Series consists of five Minireviews that highlight selected topics of current autophagy research ranging from the molecular mechanisms and regulation of autophagy to the roles of autophagy in health and disease.

Deep brain stimulation technology enables the neural modulation with precise spatial control but requires permanent implantation of conduits. Here, we describe a photothermal wireless deep brain stimulation nanosystem capable of eliminating α-synuclein aggregates and restoring degenerated dopamine neurons in the substantia nigra to treat Parkinson's disease. This nanosystem (ATB NPs) consists of gold nanoshell, an antibody against the heat-sensitive transient receptor potential vanilloid family member 1 (TRPV1), and β-synuclein (β-syn) peptides with a near infrared-responsive linker.

Atherosclerosis (AS) is a prevalent inflammatory vascular disease characterized by plaque formation, primarily composed of foam cells laden with lipids. Despite lipid-lowering therapies, effective plaque clearance remains challenging due to the overexpression of the CD47 molecule on apoptotic foam cells, inhibiting macrophage-mediated cellular efferocytosis and plaque resolution. Moreover, AS lesions are often associated with severe inflammation and oxidative stress, exacerbating disease progression.

To investigate the effect of icariin (ICA) on hepatocellular carcinoma (HCC) and its autophagy/apoptosis mechanism in HCC. The anti-HCC mechanism of ICA was investigated using HCC cells treated with 20 µmol/L ICA. Cell viability and proliferation were assessed using CCK-8 and colony formation assays, respectively, while TUNEL staining evaluated anti-apoptotic effects.
