“…In addition to cytoprotective effects, autophagy exerts a death stimulation function, known as autophagic cell death, depending on the specific conditions [4]. In the meantime, autophagy offers a therapeutic opportunity to patients with diverse diseases, such as rheumatic diseases, ischemic heart diseases, central nervous system (CNS) diseases and tumors by modulating apoptosis, inflammation, immune responses, and other intracellular processes [5–8]. Nevertheless, the defective specificity of autophagy activators or inhibitors limits their clinical applications.…”

Autophagy is a genetically well-controlled cellular process that is tightly controlled by a set of core genes, including the family of autophagy-related genes (ATG). Autophagy is a “double-edged sword” in tumors. It can promote or suppress tumor development, which depends on the cell and tissue types and the stages of tumor. At present, tumor immunotherapy is a promising treatment strategy against tumors. Recent studies have shown that autophagy significantly controls immune responses by modulating the functions of immune cells and the production of cytokines. Conversely, some cytokines and immune cells have a great effect on the function of autophagy. Therapies aiming at autophagy to enhance the immune responses and anti-tumor effects of immunotherapy have become the prospective strategy, with enhanced antigen presentation and higher sensitivity to CTLs. However, the induction of autophagy may also benefit tumor cells escape from immune surveillance and result in intrinsic resistance against anti-tumor immunotherapy. Increasing studies have proven the optimal use of either ATG inducers or inhibitors can restrain tumor growth and progression by enhancing anti-tumor immune responses and overcoming the anti-tumor immune resistance in combination with several immunotherapeutic strategies, indicating that induction or inhibition of autophagy might show us a prospective therapeutic strategy when combined with immunotherapy. In this article, the possible mechanisms of autophagy regulating immune system, and the potential applications of autophagy in tumor immunotherapy will be discussed.

“…Recently, accumulated studies reported that herbals could protect against ischemic cardiomyopathy by regulating autophagy [29]. Gingko biloba leaf extract (GBE), which contains terpenoids, flavonoids, alkylphenols, polyprenols, and organic acids, has long been used for the treatment of cardiovascular disease [30].…”

Background. There is a crosstalk between endoplasmic reticulum stress (ERS) and autophagy, and autophagy could attenuate endoplasmic reticulum stress-mediated apoptosis. Ginkgo biloba leaf extract (GBE) exerts vascular protection functions. The purpose of the present study is to investigate the role of autophagy in diabetic atherosclerosis (AS) and the effect of GBE on autophagy and ERS. Methods. Network pharmacology was utilized to predict the targets and pathways of the active chemical compounds of Gingko biloba leaf to attenuate AS. ApoE-/- mice were rendered diabetic by intraperitoneal ingestion with streptozotocin combined with a high-fat diet. The diabetic mice were divided into five groups: model group, atorvastatin group, rapamycin group, and low- and high-dose GBE groups. Serum and tissue markers of autophagy or ERS markers, including the protein expression, were examined. Results. The mammalian target of rapamycin (mTOR) and NF-κB signaling pathways were targeted by the active chemical compounds of GBE to attenuate AS predicted by network pharmacology. GBE reduced the plaque area/lumen area and the plaque lipid deposition area/intimal area and inhibited the expressions of CD68, MMP2, and MMP9. Rapamycin and GBE inhibited the expression of mTOR and SQSTM1/p62 which increased in the aorta of diabetic mice. In addition, GBE reduced the expression of ERS markers in diabetic mice. GBE reduced the serum lipid metabolism levels, blood glucose, and inflammatory cytokines. Conclusion. Impaired autophagy and overactive endoplasmic reticulum stress contributed to diabetic atherosclerosis. mTOR inhibitor rapamycin and GBE attenuated diabetic atherosclerosis by inhibiting ERS via restoration of autophagy through inhibition of mTOR.

Autophagy is a biomolecular system known to play an important role in cell growth, development as well as defense mechanisms, and is also a physiological approach towards homeostasis maintenance. This phenomenon is an intermediary pathway in the pathogenesis and therapy of various disease types, and is currently a new treatment route in the medical world. Hence, it is necessary to deeply understand the regulations, to prepare a treatment strategy in the future. Conversely, there is a high utilization of drugs, in line with the numerous disease cases in the community. Some limited chemical forms have large but necessary side effects, including anticancer agents. The high incidence of resistance and polypharmacy has been implicated in adverse drug interactions, and exorbitant costs, thus the initiative to return back to natural means. Furthermore, herbal medicines have been used in treatments for thousands of years, prior to the discovery of modern medicine. The various types previously studied have been highly beneficial in various disease cases. This review on researches within the last 5 years identified some herbal research articles in the aspect of autophagy, which was then summarized in a table form. Meanwhile, autophagy has been used for cancer therapy, and many plants have the potential to be therapeutic for various diseases through this pathway. Hence, improving related knowledge adds a new dimension to herbal medicine application in the pharmaceutical industry.Keywords: Autophagy, herbal, cancer, metabolic diseases, liver injury, neurological disorderPeran Berbagai Tanaman Herbal pada AutofagiAbstrakAutofagi adalah sistem biomolekuler sel yang berperan penting dalam pertumbuhan sel, perkembangan dan mekanisme pertahanan, dan merupakan sebuah cara fisiologis untuk mempertahankan homeostasis. Autofagi digunakan sebagai jalur perantara untuk patogenesis dan terapi berbagai jenis penyakit, dan saat ini autofagi telah menjadi jalan pengobatan baru di dunia medis sehingga regulasi jalur autofagi harus dipelajari lebih dalam untuk mempersiapkan strategi pengobatan di masa depan. Di sisi lain, tingginya pemanfaatan obat-obatan sejalan dengan banyaknya kasus penyakit yang muncul di masyarakat. Beberapa obat kimia memiliki efek samping yang besar tetapi jumlahnya terbatas, misalnya pada obat antikanker. Selain itu, tingginya kasus resistensi obat dan polifarmasi menyebabkan interaksi obat yang merugikan dan biaya obat yang tinggi. Oleh karena itu, pengobatan kini telah kembali ke alam. Herbal telah digunakan sebagai pengobatan selama ribuan tahun sebelum pengobatan modern ditemukan. Berbagai jenis herbal telah dipelajari dan memiliki manfaat yang baik dalam berbagai kasus penyakit di masyarakat. Pada artikel review ini, ditelaah artikel-artikel penelitian herbal yang mengambil jalur autofagi dan hasilnya dirangkum dalam bentuk tabel. Studi yang dilakukan dalam kurun waktu 5 tahun terakhir dimasukkan dalam review ini. Sampai sekarang, autofagi telah lebih banyak digunakan untuk terapi kanker dibandingkan yang tanpa kanker. Banyak tanaman herbal yang memiliki potensi untuk menjadi terapi berbagai jenis penyakit melalui jalur autofagi. Pengetahuan tentang autofagi menambah dimensi baru pada pengobatan herbal dan dapat diterapkan dalam industri farmasi.Kata kunci: Autofagi, gangguan metabolisme, gangguan saraf, herbal, kanker, kerusakan hati
