Modulation of immune responses in newborn and adult mice by interferon

Interferon was found to have both suppressive and enhancing effects on the antibody response in newborn and adult mice. Evidence was obtained that these effects are primarily evoked during the initial steps controlling cell proliferation. Stimulation of thymus and spleen cells with a T-cell mitogen was enhanced by low doses and suppressed by high doses of interferon. Treatment of parental spleen c

Regional specialization within the intestinal immune system.

The intestine represents the largest compartment of the immune system. It is continually exposed to antigens and immunomodulatory agents from the diet and the commensal microbiota, and it is the port of entry for many clinically important pathogens. Intestinal immune processes are also increasingly implicated in controlling disease development elsewhere in the body. In this Review, we detail the a

Early Cellular Pathways of Mouse Natural Killer Cell Development.

Natural killer (NK) cells are large granular lymphocytes that are components of the innate immune system. These cells are key players in the defense against viral and other microbial infections and cancer and have an important function during pregnancy, autoimmunity and allergy. Furthermore, NK cells play important roles in hematopoietic stem cell (HSC) transplantation by providing the graft versu

The airway epithelium as regulator of inflammation patterns in asthma

Introduction: Asthma is a complex, heterogeneous and mutifactorial disease and represents a major health problem in Westernised countries. The airway epithelium, with its direct physical contact with luminal triggers, has a major role in determining the nature of inflammation that develops in asthmatic airways. Objective: The present review aims to provide a brief overview of the numerous ways the

Impact of cell wall-degrading enzymes on water-holding capacity and solubility of dietary fibre in rye and wheat bran.

BACKGROUND: Rye and wheat bran were treated with several xylanases and endoglucanases, and the effects on physicochemical properties such as solubility, viscosity, water-holding capacity and particle size as well as the chemical composition of the soluble and insoluble fractions of the bran were studied. A large number of enzymes with well-defined activities were used. This enabled a comparison be

Internal water and microsecond dynamics in myoglobin.

Myoglobin (Mb) binds diatomic ligands, like O2, CO, and NO, in a cavity that is only transiently accessible. Crystallography and molecular simulations show that the ligands can migrate through an extensive network of transiently connected cavities but disagree on the locations and occupancy of internal hydration sites. Here, we use water (2)H and (17)O magnetic relaxation dispersion (MRD) to chara

Pre-diagnostic polyphenol intake and breast cancer survival: the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.

The aim was to investigate the association between pre-diagnostic intakes of polyphenol classes (flavonoids, lignans, phenolic acids, stilbenes, and other polyphenols) in relation to breast cancer survival (all-cause and breast cancer-specific mortality). We used data from the European Prospective Investigation into Cancer and Nutrition cohort. Pre-diagnostic usual diet was assessed using dietary

The aetiology of pharyngotonsillitis in adolescents and adults - Fusobacterium necrophorum is commonly found.

Sore throat is common in primary healthcare. Aetiological studies have focused on the presence of a limited number of pathogens. The aim of the present study was to investigate the presence of a wide range of bacteria and viruses, including Fusobacterium necrophorum, in patients with pharyngotonsillitis and in asymptomatic controls. A prospective case control study was performed in primary healthc

Antibody array generation and use.

Affinity proteomics, represented by antibody arrays, is a multiplex technology for high-throughput protein expression profiling of crude proteomes in a highly specific, sensitive, and miniaturized manner. The antibodies are individually deposited in an ordered pattern, an array, onto a solid support. Next, the sample is added, and any specifically bound proteins are detected and quantified using m

Recombinant antibodies for the generation of antibody arrays.

Affinity proteomics, mainly represented by antibody microarrays, has in recent years been established as a powerful tool for high-throughput (disease) proteomics. The technology can be used to generate detailed protein expression profiles, or protein maps, of focused set of proteins in crude proteomes and potentially even high-resolution portraits of entire proteomes. The technology provides uniqu

Prevention of superantigen induced down-regulation of T cell mediated cytotoxic activity by IL-2 in vivo. 1996 Accepted for publication in Immunology

Administration of staphylococcal enterotoxin A (SEA) to mice induces profound activation, cytokine production and cytotoxic activity of both CD4+ and CD8+ T cells, but subsequently activated cells are deleted or become anergic. This study demonstrates that administration of interleukin-2 (IL-2) can prevent sea-induced hyporesponsiveness in CD8+ cytotoxic T lymphocytes (CTL). Repeated injections wi
