Macrophage subsets and liver diseases

Macrophage subsets in human atherosclerosis.

Pathophysiological relevance of macrophage subsets in atherogenesis.

Macrophages are highly heterogeneous and plastic cells. They were shown to play a critical role in all stages of atherogenesis, from the initiation to the necrotic core formation and plaque rupture. Lesional macrophages primarily derive from blood monocyte, but local macrophage proliferation as well as differentiation from smooth muscle cells have also been described. Within atherosclerotic pla...

Identification of polarized macrophage subsets in zebrafish

While the mammalian macrophage phenotypes have been intensively studied in vitro, the dynamic of their phenotypic polarization has never been investigated in live vertebrates. We used the zebrafish as a live model to identify and trail macrophage subtypes. We generated a transgenic line whose macrophages expressing tumour necrosis factor alpha (tnfa), a key feature of classically activated (M1)...

Fecal Microbiota Transplantation in Liver Diseases and Recent Developments

Introduction: The intestine, as an important part of the human gastrointestinal tract, provides a favorable milieu for the growth and development of a diverse and large population (approximately 1000 species) of bacteria. Currently, the presence of a cohesive relationship between intestinal bacteria and the host is being well studied and identified. According to the available scientific evidenc...

Splenic Macrophage Subsets and Their Function during Blood-Borne Infections

The spleen is one of the major immunological sites for maintaining blood homeostasis. Previous studies showed that heterogeneous splenic macrophage populations contribute in complimentary ways to control blood-borne infections and induce effective immune responses. Marginal metallophilic macrophages (MMMΦs) and marginal zone macrophages (MZMΦs) are cells with great ability to internalize blood-...
