In addition to the cytokines and cell signaling molecules mentioned above, the HSC niche in the bone marrow provides soluble factors, forces, and cell-mediated interactions necessary to maintain the hematopoietic potential of the stem cells located there. This niche is generally separated into 2 sections:
Pyelonephritis is inflammation that results from a urinary tract infection that reaches the renal pelvis of the kidney. [6] Lupus nephritis is inflammation of the kidney caused by systemic lupus erythematosus (SLE), a disease of the immune system. [7] Athletic nephritis is nephritis resulting from strenuous exercise. [8]
Bone marrow failure in both children and adults can be either inherited or acquired. Inherited bone marrow failure is often the cause in young children, while older children and adults may acquire the disease later in life. [3] Acquired bone marrow failure may be due to aplastic anemia [4] or myelodysplastic syndrome.
Nephritic syndrome is a syndrome comprising signs of nephritis, which is kidney disease involving inflammation. It often occurs in the glomerulus, where it is called glomerulonephritis. Glomerulonephritis is characterized by inflammation and thinning of the glomerular basement membrane and the occurrence of small pores in the podocytes of the ...
That bone marrow is a priming site for T-cell responses to blood-borne antigens was first described in 2003. [13] Mature circulating naïve T cells home to bone marrow sinuses after they have passed through arteries and arterioles. [14] They transmigrate sinus endothelium and enter the parenchyma which contains dendritic cells (DCs).
Myeloid tissue, in the bone marrow sense of the word myeloid (myelo-+ -oid), is tissue of bone marrow, of bone marrow cell lineage, or resembling bone marrow, and myelogenous tissue (myelo-+ -genous) is any tissue of, or arising from, bone marrow; in these senses the terms are usually used synonymously, as for example with chronic myeloid ...
Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [1] but not all diseases necessarily have an inflammatory component.
This filtrate then flows along the length of the nephron, which is a tubular structure lined by a single layer of specialized cells and surrounded by capillaries. The major functions of these lining cells are the reabsorption of water and small molecules from the filtrate into the blood, and the secretion of wastes from the blood into the urine.
