Damaged cells are cleared by macrophages in the spleen, where the precipitate and damaged membrane are removed, leading to characteristic "bite cells". The denaturing process is irreversible and the continual elimination of damaged cells leads to Heinz body anemia. There are several pathways leading to the hemoglobin damage.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to the red blood cells adopting an abnormal ...
Anthony Clifford Allison (21 August 1925 – 20 February 2014) was a South African geneticist and medical scientist who made pioneering studies on the genetic resistance to malaria. [2] Allison undertook his primary schooling in Kenya, completed his higher education in South Africa, and obtained a BSc in medical science from the University of ...
Hematology. Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous). Those who are heterozygous for the sickle cell allele produce both ...
Echinocyte. Echinocyte (from the Greek word echinos, meaning 'hedgehog' or 'sea urchin'), in human biology and medicine, refers to a form of red blood cell that has an abnormal cell membrane characterized by many small, evenly spaced thorny projections. [1][2] A more common term for these cells is burr cells.
Sickle cell disease is a blood disorder that affects red blood cells’ ability to carry oxygen to other parts of the body due to an abnormal sickle-like shape, which increases the risk of other ...
Döhle bodies are light blue-gray, oval, basophilic, leukocyte inclusions located in the peripheral cytoplasm of neutrophils. They measure 1–3 μm in diameter. Not much is known about their formation, but they are thought to be remnants of the rough endoplasmic reticulum. [citation needed] They are named after German pathologist, Karl ...
One of the drugmakers, Bluebird Bio, in August cut its forecast for use of all three of its gene therapy products this year to 85 at most, down from 105. Earlier this week, it said 10 patients had ...
