Because of the ongoing pandemic around world, mechanisms underlying SARS-CoV-2-induced COVID-19 are subject to intense investigation. Based on available data for SARS-CoV-1 virus, we suggest how CoV-2 localization RNA transcripts in mitochondria hijacks host cell’s mitochondrial function viral advantage. Besides transcripts, also localizes mitochondria. SARS-CoV-2 may manipulate indirectly, first by ACE2 regulation function, and once it enters cell, open-reading frames (ORFs) such as ORF-9b can directly evade cell immunity facilitate virus replication disease. Manipulations ORFs release DNA (mtDNA) cytoplasm activate mtDNA-induced inflammasome suppress innate adaptive immunity. We argue that a decline aged individuals, coupled with age-associated functions resulting chronic metabolic disorders like diabetes or cancer, make more vulnerable infection health complications mortality. These observations distinct proteins must play essential roles pathogenesis. Understanding communication provide critical insights into pathologies. An investigation hijacking should lead novel approaches prevent treat COVID-19.

Glycolysis has long been considered as the major metabolic process for energy production and anabolic growth in cancer cells. Although such a view instrumental development of powerful imaging tools that are still used clinics, it is now clear mitochondria play key role oncogenesis. Besides exerting central bioenergetic functions, provide indeed building blocks tumor anabolism, control redox calcium homeostasis, participate transcriptional regulation, govern cell death. Thus, constitute promising targets novel anticancer agents. However, tumors arise, progress, respond to therapy context an intimate crosstalk with host immune system, many immunological functions rely on intact mitochondrial metabolism. Here, we review cell-intrinsic cell-extrinsic mechanisms through which influence all steps oncogenesis, focus therapeutic potential targeting metabolism therapy.

Aging is the progressive loss of organ and tissue function over time. Growing older positively linked to cognitive biological degeneration such as physical frailty, psychological impairment, decline. Oxidative stress considered an imbalance between pro- antioxidant species, which results in molecular cellular damage. plays a crucial role development age-related diseases. Emerging research evidence has suggested that can control autoxidation by interrupting propagation free radicals or inhibiting formation subsequently reduce oxidative stress, improve immune function, increase healthy longevity. Indeed, oxidation damage highly dependent on inherited acquired defects enzymes involved redox-mediated signaling pathways. Therefore, molecules with activity promote aging counteract worth discuss further.

Abstract In recent years, immunotherapy represented by immune checkpoint inhibitors (ICIs) has led to unprecedented breakthroughs in cancer treatment. However, the fact that many tumors respond poorly or even not ICIs, partly caused absence of tumor-infiltrating lymphocytes (TILs), significantly limits application ICIs. Converting these “cold” into “hot” may ICIs is an unsolved question immunotherapy. Since it a general characteristic cancers resist apoptosis, induction non-apoptotic regulated cell death (RCD) emerging as new treatment strategy. Recently, several studies have revealed interaction between RCD and antitumor immunity. Specifically, autophagy, ferroptosis, pyroptosis, necroptosis exhibit synergistic responses while possibly exerting inhibitory effects on responses. Thus, targeted therapies (inducers inhibitors) against combination with exert potent activity, resistant This review summarizes multilevel relationship immunity RCD, including necroptosis, potential targeting improve efficacy malignancy.
