The role of monocytes in ANCA-associated vasculitides

The anti – neutrophil cytoplasm antibody (ANCA) – associated vasculitides (AAV) include granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). These rare systemic autoimmune diseases affect small and medium – sized blood vessels, and are characterized by necrotizing vasculitis,

The gods of human T cell development

T cells are the component of the immune system required for recognizing and targeting pathogens and tumor cells. Because each T cell recognizes a different pathogen, the challenge of T cell development is to create a pool

Identification of a new T cell regulator

T-cell receptor (TCR) signaling is mediated by the activation of protein-tyrosine kinases such as p56lck and ZAP-70. In mature T-cells, CD4 and CD8 molecules bind to p56lck which then phosphorylates the intracellular immune-receptor tyrosine-based activation motifs (ITAM)

Oocyte activation and latent HIV-1 reactivation: AMPK links the creation of all human life and the potential eradication of HIV-1

In an active area of research known as HIV-1 cure research, the purposeful reactivation of latent/dormant HIV-1 in memory T cells, which induces death of the infected cell or alerts the immune system to the presence of

Hyper IgM syndrome in North America: a rare disease of a critical step in the immune response pathway

Hyper IgM (HIGM) syndromes are a group of rare genetic disorders leading to ineffective immune responses. People with this immune defect are usually diagnosed in early childhood due to frequent infections. Most of these are common but

BRAF inhibitor and interferon alpha combination for melanoma treatment

In recent years approval has been granted to many therapeutic agents for the treatment of patients with metastatic melanoma. They include small molecule inhibitors, such as the selective inhibitors of the mutant BRAF (BRAF-I) or of MEK (MEK-I), and

How Vitamin C affects the immune system

DNA contains four bases, A, C, G and T (Fig.1). There are 3 billion of these bases in the human genome, and they code for about 22,000 genes. Because each cell carries the same genetic information –

Zinc – A beneficial player in autoimmune diseases

Essential trace elements, especially zinc, are indispensable for a proper immune function. Zinc deficiency or excess causes severe impairment of the immune response. So far, an increased susceptibility to infections, increased number of transplant rejections, development of

Aberrantly methylated DNA regions in IgA Nephropathy patients affect the disease

The genome can influence the onset and the development of the diseases in several manner, and in the last years several studies have revealed the new role of the DNA methylation in this framework. The DNA methylation

Special molecular mechanism makes CD147 an interesting drug target in cancer or autoimmune diseases

T cells are important players of the immune system, recognizing foreign or dangerous agents with their unique receptors. They defend the body from these agents either directly by killing or by recruiting or regulating other immune system

Vitamin D and T cells in multiple sclerosis: how to measure an effect?

Multiple sclerosis (MS) is an inflammatory disease of the brain, leading to disability in patients suffering from this disease. A type of white blood cells, T cells, are important pathogenic cells which drive this inflammation in early

The stromal vascular fraction: a regenerative reality?

In 2001, researchers discovered that fat tissue contains stem cells, which they termed adipose derived stem cells (ADSCs). To obtain these stem cells, fat tissue is taken from the abdomen of healthy adults undergoing liposuction and processed

B cells to the rescue: regulatory B cells are a promising therapeutic target for autoimmune disease

Immune cells are indispensable for protecting us from microbial infections. They recognize specific patterns on microbes to mount robust cellular and molecular immune responses for the clearance of pathogens. Intriguingly, development and function of these cells is
