Probiotic bacteria express a wide range of molecular structures that bind to receptors on innate immune cells and mediate health-promoting effects in the host. We have recently demonstrated in a colitis model that favourable effects of the probiotic mixture VSL#3 may in part be due to the suppression of intestinal chemokine expression. To obtain...

Background: Wet-wrap treatment (WWT) with diluted topical steroids is widely used in atopic dermatitis (AD). Mice with transgenic overexpression of human apolipoprotein C1 (APOC1) in the liver and the skin are not only characterized by hyperlipidaemia and raised IgE levels, but also by pruritic dermatitis and a disturbed skin barrier function,...

Tolerance to experimental autoimmune encephalomyelitis (EAE) in SJL mice can be induced by immunization with a mannosylated form of the proteolipid protein (M-PLP139-151), despite the presence of CFA. The state of tolerance is characterized by poor delayed-type hypersensitivity responses and the absence of clinical EAE symptoms. In vivo...

In this study, we investigated the development of T cell responses in mice after administration of a mannosylated ovalbumin peptide (M-OVA323-339). Immunization with M-OVA323-339 in complete adjuvant resulted in enhanced antigen presentation in draining lymph nodes. Monitoring the fate of CFSE-labeled ovalbumin peptide-specific TCR transgenic...

Mice with transgenic expression of human apolipoprotein C1 (APOC1) in liver and skin have strongly increased serum levels of cholesterol, triglycerides, and free fatty acids, indicative of a disturbed lipid metabolism. Importantly, these mice display a disturbed skin barrier function, evident from increased transepidermal water loss, and...

We have previously shown that immunization with a mannosylated myelin peptide in complete adjuvant induces tolerance instead of disease in experimental autoimmune encephalomyelitis (EAE), a rodent model for multiple sclerosis. In this report we demonstrate that treatment with a soluble mannosylated epitope of proteolipid protein (M-PLP139-151)...

Objective: Inflammatory factors are thought to play a regulatory role in restenosis. Interleukin-10 (IL10) is an important anti-inflammatory cytokine with anti-atherogenic potentials. The aim of this study was to assess the effects of IL10 modulation on cuff-induced neointima formation in hypercholesterolemic APOE*3-Leiden mice. Methods: The...

SJL mice immunized with mannosylated (M-) PLP139-151 in complete adjuvant do not develop EAE and little CNS mononuclear cell infiltration; other mannosylated peptides were ineffective in this experimental setting. Despite apparently normal T cell responses, M-PLP139-151-immunized mice show impaired delayed-type-sensitivity to PLP139-151 but a...

Background: The dogma in psoriasis is that due to pathogen-induced inflammatory responses, an autoreactive immune response is induced that leads to tissue destruction. However, this model might be too simplistic. Literature data suggest that the expression of enzymes crucial for fatty acid oxidation is upregulated in the skin of patients with...

It has been demonstrated that anti-CD154 mAb treatment effectively inhibits the development of experimental autoimmune encephalomyelitis (EAE). However, although it appears to prevent the induction of Th1 cells and reactivation of encephalitogenic T cells within the CNS, little information is available regarding the involvement of alternative...

In this study, mouse recombinant IFN-β was shown to favor PLP139-151-specific Th2 responses in vitro, by inhibiting IFN-γ production and stimulating IL-4 and IL-10 production. IFN-β (5000 U/day) failed to prevent the development or severity of EAE induced with PLP139-151. Whereas efficacy of IL-10 was found in the B. pertussis assisted but not...

IL-10 and IL-4 were studied with respect to their capacity to inhibit experimental allergic encephalomyelitis (EAE) induced in SJL/J mice by immunization with the proteolipid protein peptide PLP139-151. Treatment with 2 μg IL-10/day from day 0 until day 12 delayed onset of disease and inhibited the severity of EAE. By contrast, a daily dose of 0...

In the present study we investigated whether age-related changes in the composition and functional properties of murine CD4+ T cells are reflected in vivo by a changed humoral response to influenza vaccine in aged mice. After the primary immunization, the titers of influenza-specific IgM, IgG1, IgG2a, and IgG2b, but not of IgG3 and IgE, were...

CD4+ T cells from young and aged mice were sorted into Mel-14+ cells which are regarded as naive cells and Mel-14- cells which are regarded as memory cells. These subsets were stimulated in short-time cultures with anti-CD3 or anti-CD3/anti-CD28 in order to determine the presence of Th1 and/or Th2 cytokines. Based on the simultaneous production...

Stimulation of murine CD4+ T cells with staphylococcal enterotoxin B (SEB) results in the preferential development of T helper (Th) 1 cells [i.e. high interferon (IFN)-γ and low interleukin (IL)-4, IL-5 and IL-10]; whereas in response to plate-bound anti-CD3 or anti-T cell receptor-αβ, Th1 as well as Th2 cells develop. In the present study, we...

Aging is accompanied by a decline in immune reactivity which to a major extent can be attributed to changes at the level of the regulatory CD4+ T cells. In addition to evidence pointing to intrinsic defects, resulting in improper responsiveness of lymphocytes, it is likely that many age-related phenomena can be explained by a changed composition...
