Oxidative Stress in Chronic Obstructive Pulmonary Disease
Since chronic obstructive pulmonary disease (COPD) is a heterogeneous disease, a specific anti-inflammatory therapy for this disease has not been established yet. Oxidative stress is recognized as a major predisposing factor to COPD related inflammatory responses, resulting in pathological features of small airway fibrosis and emphysema.

Extracellular Vesicles in Atherothrombosis
Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of morbidity and mortality all over the world. Extracellular vesicles (EVs), small lipid-bilayer membrane vesicles released by most cellular types, exert pivotal and multifaceted roles in physiology and disease. Emerging evidence emphasizes the importance of EVs in intercellular communication processes with key effects on cell survival, endothelial homeostasis, inflammation, neoangiogenesis, and thrombosis. The following content focuses on EVs as effective signaling molecules able to both derail vascular homeostasis and induce vascular dysfunction, inflammation, plaque progression, and thrombus formation as well as drive anti-inflammation, vascular repair, and atheroprotection.

PD-1/PD-L1 Therapy in Non-alcoholic Fatty Liver Disease
Non-alcoholic fatty liver disease (NAFLD) is characterized by an enhanced activation of the immune system, which predispose the evolution to nonalcoholic steatohepatitis (NASH) and hepatocellular carcinoma (HCC). Resident macrophages and leukocytes exert a key role in the pathogenesis of NAFLD. In particular, CD4+ effector T cells are activated during the early stages of liver inflammation and are followed by the increase of natural killer T cells and of CD8+ T cytotoxic lymphocytes which contribute to auto-aggressive tissue damage. To counteract T cells activation, programmed cell death 1 (PD-1) and its ligand PDL-1 are exposed respectively on lymphocytes and liver cells’ surface and can be targeted for therapy by using specific monoclonal antibodies, such as of Nivolumab, Pembrolizumab and Atezolizumab.

Oxidation of Antipsychotics
Antipsychotics (APs) are psychotropic drugs that generally have a psycholeptic effect, capable of reducing psychotic symptoms and psychomotor agitation. This class of drugs is widely used in psychiatric practice, especially for the treatment of psychosis in schizophrenia and other psychotic disorders. Most APs pass through a biotransformation process, or metabolism, after they enter the body before being eliminated. There are three phases of AP metabolism. Cytochrome P450 (CYP) monooxygenase (mixed-function oxidase) plays a central role in most AP biotransformation. CYP’s functional activity depends on gene–drug and drug–drug interaction and influences on the occurrence of adverse drug reactions (ADRs). So, it is extremely important for a practicing psychiatrist to know the oxidation pathway of APs, since most of them are metabolized in the liver. This is important both to prevent ADRs and to avoid unwanted drug–drug interactions, which will undoubtedly increase the effectiveness and safety of AP therapy.

Polymyxins
Polymyxins are non-ribosomal, cyclic oligopeptide antimicrobials, produced by the Gram-positive, spore-forming rod Bacillus aerosporus that were identified in 1946 from the soil of market gardens in England.

Placenta Extract on Liver
The placenta contains multiple biologically active substances, which exert antioxidation, anti-inflammatory, immunomodulatory, and delayed aging effects. Its extract can improve hepatic morphology and function: on the one hand, it can reduce liver interstitial collagen deposition, lipogenesis, and inflammatory cell infiltration and improve fibrosis; on the other hand, it can prevent hepatocellular degeneration by scavenging reactive oxygen species (ROS) and inhibiting inflammatory cytokine production, further improve hepatocyte apoptosis and necrosis, and promote hepatocyte regeneration, making it a promising liver-protective agent.

Small Fiber Neuropathy in Sarcoidosis
Sarcoidosis (SC) is a granulomatous disease of an unknown origin. The most common SC-related neurological complication is a small fiber neuropathy (SFN) that is often considered to be the result of chronic inflammation and remains significantly understudied.

Wickerhamomyces Yeast Killer Toxins
Bacteriocins are ribosomally synthesized antimicrobial peptides produced from a wide variety of bacteria that inhibit the growth of similar or closely related bacterial strains. A similar phenomenon of competition is present in yeasts, based on the production of killer toxins (KTs, or mycocins) that are secreted proteins or glycoproteins capable of killing susceptible microorganisms with various mechanisms of action, through interaction with specific superficial receptors. Possible implications and applications of the yeast killer phenomenon in the fight against infectious diseases are reviewed in this work, with particular reference to some wide-spectrum killer toxins (KTs) produced by Wickerhamomyces anomalus and other related species.
