Downie Bodies
Downie bodies, also known as a type of A-type inclusion, are a type of inclusion body associated with cowpox. They are named for Allan Watt Downie. A Downie body is different from a ''Downey cell'' which is a reactive lymphocyte In immunology, reactive lymphocytes or variant lymphocytes are cytotoxic (CD8+) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 μm in diameter with varying size and shape. The nucleus of .... They are named for Hal Downey. References Viral diseases Histopathology {{virus-stub ...

Inclusion Body
Inclusion bodies are aggregates of specific types of protein found in neurons, a number of tissue cells including red blood cells, bacteria, viruses, and plants. Inclusion bodies of aggregations of multiple proteins are also found in muscle cells affected by inclusion body myositis and hereditary inclusion body myopathy. Inclusion bodies in neurons may be accumulated in the cytoplasm or nucleus, and are associated with many neurodegenerative diseases. Inclusion bodies in neurodegenerative diseases are aggregates of misfolded proteins (aggresomes) and are hallmarks of many of these diseases, including Lewy bodies in Lewy body dementias, and Parkinson's disease, neuroserpin inclusion bodies called Collins bodies in familial encephalopathy with neuroserpin inclusion bodies, inclusion bodies in Huntington's disease, Papp-Lantos inclusions in multiple system atrophy, and various inclusion bodies in frontotemporal dementia including Pick bodies. Bunina bodies in motor neurons are a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cowpox
Cowpox is an infectious disease caused by the ''cowpox virus'' (CPXV). It presents with large blisters in the skin, a fever and swollen glands, historically typically following contact with an infected cow, though in the last several decades more often (though overall rarely) from infected cats. The hands and face are most frequently affected and the spots are generally very painful. The virus, part of the genus '' Orthopoxvirus'', is closely related to the ''vaccinia'' virus. The virus is zoonotic, meaning that it is transferable between species, such as from cat to human. The transferral of the disease was first observed in dairymaids who touched the udders of infected cows and consequently developed the signature pustules on their hands.Vanessa Ngan, "Viral and Skin Infections" 2009 Cowpox is more com ...

Reactive Lymphocyte
In immunology, reactive lymphocytes or variant lymphocytes are cytotoxic (CD8+) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 μm in diameter with varying size and shape. The nucleus of a reactive lymphocyte can be round, elliptic, indented, cleft, or folded. The cytoplasm is often abundant and can be basophilic. Vacuoles and/or azurophilic granules are also sometimes present. Most often, the cytoplasm is gray, pale blue, or deep blue in colour. The distinctive cell associated with EBV or CMV is known as a "Downey cell", after Hal Downey, who contributed to the characterization of it in 1923. __TOC__ Causes Reactive lymphocytes are usually associated with viral illnesses, but they can also be present as a result of drug reactions (such as phenytoin), immunizations, radiation, and hormonal causes (such as stress and Addison's disease), as well as some autoimmune disorders (such as rheumatoid arthritis). Some pathog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
