Acanthocyte Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in human biology and medicine, refers to a form of red blood cell that has a spiked cell membrane, due to abnormal thorny projections. A similar term is spur cells.canthocytosis can be seen in: Acute or Chronic Anemia, Hepatitis A,B,C; Hepatorenal syndrome, Hypopitutarism, Malabsorption Syndromes, Malnutrition In malnourishment, such as anorexia nervosa and cystic fibrosis, acanthocytosis remits with resolution of the nutritional deficiency.

Leukocytes Leukocytes are another word for white blood cells or WBCs. These are a crucial part of the immune system as they defend our bodies from infectious diseases and foreign materials.

Natural killer cell Natural killer cells or NK cells are a type of cytotoxic lymphocyte critical to the innate immune system.his role of NK cells is critical to immune success particularly because T cells are unable to recognize pathogens in the absence of surface antigens. Tumor cell detection results in activation of NK cells and consequent cytokine production and release.

Granulocyte Granulocytes are a type of white blood cell that has small granules, which contain proteins. The specific types of granulocytes are neutrophils, eosinophils, and basophils. Granulocytes, specifically neutrophils, help the body fight bacterial infections. The number of granulocytes in the body usually increases when there is a serious infection. People with a lower number of granulocytes are more likely to develop bad infections more often. Granulocytes are counted as part of a white blood cell differential test.

- Dendritic cells are a type of antigen-presenting cell (APC) that form an important role in the adaptive immune system.endritic cells are found in tissue that has contact with the outside environment such as the over the skin (present as Langerhans cells) and in the linings of the nose, lungs, stomach and intestines. Immature forms are also found in the blood.

Echinocyte From Wikipedia, the free encyclopedia. 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.A more common term for these cells is burr cells.chinocytes, like acanthocytes, may be found in hyperlipidemia caused by liver dysfunction, but the lipids themselves do not integrate into the membrane. Instead, it is speculated that cell surface receptors on the red blood cells bind with HDL cholesterol which induces the shape change.

Agranulocytosis White blood cells fight infections from bacteria, viruses, fungi, and other germs. One important type of white blood cell is the granulocyte, which is made in the bone marrow and travels in the blood throughout the body. Granulocytes sense infections, gather at sites of infection, and destroy the germs. When the body has too few granulocytes, the condition is called agranulocytosis.

- ACVS. Stem cells are undifferentiated cells that have the ability to re plicate and differentiate into a diverse range of cell types. These cell types include tendon, ligament, cartilage, muscle and bone. There are two basic types of stem cells, hematopoetic and mesenchymal.

Agranulocyte Agranulocytes, also known as mononuclear leukocytes, are white blood cells with a one-lobed nucleus. They are characterized by the absence of granules in their cytoplasm, which distinguishes them from granulocytes. Normal hematologic blood values of MLs are about 35% of all white blood cells. The 2 types of agranulocytes in the blood circulation are lymphocytes and monocytes.

- 3D Rendering of a Monocyte. Monocytes are a type of white blood cells (leukocytes). They are the largest of all leukocytes. They are part of the innate immune system of vertebrates including all mammals (humans included), birds, reptiles, and fish. They are amoeboid in shape, having agranulated cytoplasm. Monocytes have unilobar nuclei, which makes them one of the types of mononuclear leukocytes (containing azurophil granules).

Antigen-presenting cell Antigen presentation stimulates T cells to become either cytotoxic CD8+ cells or helper CD4+ cells. An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs).

Glial Cells *Release chemicals that promote the formation of tight junctions between the endothelial cells of capillaries. -These endothelial cells and tight junctions form the blood-brain barrier. *Reactive astrocytosis - Respond to tissue damage in the CNS. -In response to injuries of CNS tissue, astrocytes participate in walling off the injury site and limiting the spread of inflammation into healthy tissue.

Innate lymphoid cell Innate lymphoid cells (ILCs) are a group of innate immune cells that belong to the lymphoid lineage but do not respond in an antigen-specific manner, as they lack a B or T cell receptor. Natural killer ('NK') cells are cytotoxic innate effector cells analogous to the cytotoxic T cells of the adaptive immune system. 2  They are distributed throughout the blood, organs, and lymphoid tissue and make up around 15% of the peripheral blood lymphocytes.

Cartilage: Introduction and Overview The cells embedded in the matrix are called chondrocytes. Chondrocytes are mature cartilage cells derived from precursor cells called chondroblasts. Chondrocytes exhibit two important functional characteristics: 1  They synthesize the organic components of the extracellular matrix (this activity is significantly reduced in older chondrocytes) 2  They are capable of undergoing proliferation - the cellular basis of the internal growth of cartilage.

Neutrophil Neutrophil, type of white blood cell (leukocyte) that is characterized histologically by its ability to be stained by neutral dyes and functionally by its role in mediating immune responses against infectious microorganisms. Neutrophils, along with eosinophils and basophils, constitute a group of white blood cells known as granulocytes.

Medical Terminology for Cancer 1 Neutrophils: are the most abundant type of white blood cells and are an important part of the innate immune system. 2  Neutrophils are a type of phagocyte (cells which engulf and then digest, cellular debris and pathogens). Lymphocytes initially develop in the bone marrow. 2  Some migrate to the thymus, where they mature into T cells; others mature in the bone marrow as B cells. 3  Neutrophils: are the most abundant type of white blood cells and are an important part of the innate immune system.
