Foam cells, also called lipid-laden macrophages, are a type of cell that contain cholesterol. These can form a plaque that can lead to atherosclerosis and trigger myocardial infarction and stroke. [1] [2] [3] Foam cells are fat-laden cells with a M2 macrophage-like phenotype.
Lipid-laden alveolar macrophages, also known as pulmonary foam cells, [2] are cells found in bronchoalveolar lavage (BAL) specimens that consist of macrophages containing deposits of lipids (fats). [3] The lipid content of the macrophages can be demonstrated using a lipid targeting stain like Oil Red O or Nile red.
An electron micrograph of a macrophage. This is the general morphology of macrophages. The anatomy of human skin. Dermal macrophages are usually present in the dermis and around hair follicles. Dermal macrophages are macrophages in the skin that facilitate skin homeostasis by mediating wound repair, hair growth, and salt balance. [1]
Micrograph showing hemosiderin-laden alveolar macrophages, as seen in a pulmonary hemorrhage. H&E stain. An alveolar macrophage, pulmonary macrophage, (or dust cell) is a type of macrophage, a professional phagocyte, found in the airways and at the level of the alveoli in the lungs, but separated from their walls. [1]
The monocyte is formed in the bone marrow and transported by the blood; it migrates into the tissues, where it transforms into a histiocyte or a macrophage. Macrophages are diffusely scattered in the connective tissue and in liver (Kupffer cells), spleen and lymph nodes (sinus histiocytes), lungs (alveolar macrophages), and central nervous ...
A number of studies have linked red wine consumption with heart health benefits, including reduced LDL (known as “bad”) cholesterol levels, better blood pressure and blood vessel function and ...
Red arrows indicate secreted lamellar bodies, and green arrows indicate lamellar bodies in the cytoplasm. Scale bar = 200 nm. In cell biology, lamellar bodies (otherwise known as lamellar granules, membrane-coating granules (MCGs), keratinosomes or Odland bodies) are secretory organelles found in type II alveolar cells in the lungs, and in keratinocytes in the skin.
(Reuters) - Merck said on Monday its drug, Winrevair, helped significantly reduce the risk of death in patients with a rare condition which causes high blood pressure in the lungs, months after it ...
