Two novel immunization strategies for epidemic control in directed scale-free networks with nonlinear infectivity [PDF]
arXiv, 2018 In this paper, we propose two novel immunization strategies, i.e., combined immunization and duplex immunization, for SIS model in directed scale-free networks, and obtain the epidemic thresholds for them with linear and nonlinear infectivities. With the suggested two new strategies, the epidemic thresholds after immunization are greatly increased. For

An overview of the immune system
Nursing Standard, 2008 The immune system comprises: physical and chemical barriers; the non-specific immune mechanisms, which bring about inflammation; and the specific immune system, which recognises and memorises foreign antigens [see glossary on page 55]. The immune system depends on white blood cells that play a key role in protecting the body from invasion by pathogenic

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells
Molecular Oncology, EarlyView.In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

Immuno-epidemiology of a population structured by immune status: a mathematical study of waning immunity and immune system boosting [PDF]
arXiv, 2014 When the body gets infected by a pathogen the immune system develops pathogen-specific immunity. Induced immunity decays in time and years after recovery the host might become susceptible again. Exposure to the pathogen in the environment boosts the immune system thus prolonging the time in which a recovered individual is immune.

Sexual-dimorphism in human immune system aging
Nature Communications, 2019 Differences in immune function and responses contribute to health- and life-span disparities between sexes. However, the role of sex in immune system aging is not well understood.

Molecular Oncology, EarlyView.Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

Theoretical Aspects of Immunity [PDF]
arXiv, 2010 The immune system recognizes a myriad of invading pathogens and their toxic products. It does so with a finite repertoire of antibodies and T cell receptors. We here describe theories that quantify the immune system dynamics. We describe how the immune system recognizes antigens by searching the large space of receptor molecules.

Cross-genetic determination of maternal and neonatal immune mediators during pregnancy. [PDF]
, 2018 BACKGROUND:The immune system plays a fundamental role in development during pregnancy and early life. Alterations in circulating maternal and neonatal immune mediators have been associated with pregnancy complications as well as susceptibility to ...

Comparative Immunology, Microbiology and Infectious Diseases, 1992 Immunological features of feline lymphocytes, immunoglobulins, monocytes/macrophages, cytokines, major histocompatibility complex and delayed-type hypersensitivity are reviewed. Attention is given to the comparison of the feline immune system with the immune systems of humans and other animals.

Beneficial Effects of Probiotic Consumption on the Immune System
Annals of Nutrition and Metabolism, 2019 Background: The gastrointestinal tract is one of the most microbiologically active ecosystems that plays a crucial role in the working of the mucosal immune system (MIS). In this ecosystem, the consumed probiotics stimulate the immune system and induce a
