Abstract

Foodborne disease like salmonellosis and toxoplasmosis are amongst the most significant causes of hospitalization in the U.S. and globally. Gastrointestinal infections alter gut microbiomes and increase permeability to toxins. Various invasions by microbial, fungal, viral and parasitic agents stimulate inflammation, a defensive mechanism of the body’s immune system. Other stimuli include environmental stimuli, oxidative stress, aging and the physiological process. A long-lasting, persistent and excessive inflammatory response is a significant risk factor for developing various chronic inflammatory and infectious diseases.Different nutritional and dietary life styles, whether poor or lacking essential nutritional elements, as well as excess intake, can result in inflammatory complications and loss of function. Nutritional deficiency is linked with several infectious and inflammatory diseases as a cause or consequence. For instance, protein deficiency was reported in orphanages to provoke microbial and fungal complications including Pneumocystis pneumonia. Similarly, protein deficiency is a tell-tale sign of several parasitic diseases. Studies indicate that nutrients, such as amino acids, oligosaccharides, and short-chain fatty acids exert inhibitory and anti-inflammatory functions. These investigations help to understand nutritional contributions to the prevention, treatment and taming of certain inflammatory and infectious diseases. Infectious and inflammatory complications go hand-in-hand with malnutrition.The purpose of this Special Issue is to publish related new, basic and translational findings and clinical trials in this area. Other investigations or review articles were sought to link infectious and inflammatory diseases with nutrients. In addition, novel diagnostic, preventive and therapeutic modalities were invited to aid the development of nutritional strategies for the treatment and/or prevention of inflammation and infection. Original reviews were of particular interest to advance our understanding of signaling pathways, and the molecular and biochemical mechanisms behind the effects of nutrients on inflammatory and infectious diseases.

Abstract

The interest in human polyomaviruses (HPyV) has seen a renaissance because of new species that have been isolated and their previously unknown association with diseases. Likewise, the increasing evidence for the association of human papillomaviruses (HPV) with oropharyngeal cancer has sparked the attention of researchers and clinicians. The Special Issue “Human Polyomaviruses and Papillomaviruses” presents studies describing the nuclear egress of BK polyomavirus mediated by the viral agnoprotein and the cellular -SNAP protein. In addition, a study examines the promoter activity of two different variants of human polyomavirus 9 in different cell lines. This Special Issue offers an interesting perspective on the epidemiology of HR-HPV in different cancers and on the mechanisms by which these viruses target host cell proteins to replicate their genome, express their genes, interfere with autophagy, and induce cancer. Other topics that are highlighted include the role of co-factors, such as smoking and co-infection, novel therapeutic strategies, and surface immunoregulatory proteins, chemokines, and cytokines as possible biomarkers to determine the stage of a tumor and to predict clinical outcomes.

Abstract

Vitamin C is a pivotal water soluble electron donor in nature and an essential nutrient in man. Despite its many years as a research focus, new and increasingly regulatory functions of vitamin C in human health are continually being unravelled. This improved mechanistic insight is starting to provide rationales explaining the extensive epidemiological literature that, for decades, has consistently shown strong associations between poor vitamin C status and increased morbidity and mortality.In this Special Issue, we include original research and literature reviews by experts in the field outlining the roles of vitamin C in early, daily and late life, as well as the roles of deficiency in cardiovascular disease, inflammation and cancer.
