unusual facts about immunodeficiency



Doe v. Southeastern Pennsylvania Transportation Authority

John Doe was an employee for the Southeastern Pennsylvania Transportation Authority SEPTA who had contracted Acquired Immunodeficiency Syndrome HIV/AIDS.

Histidine kinase

A two-component system, involving histidine kinase and a variable response regulator protein, may be critical to the virulence of some fungal strains such as Candida albicans, which is often responsible for causing candidiasis in immunocompromised persons.

History of HIV/AIDS

Non-human SIVs contain a nef gene that down-regulates CD3, CD4, and MHC class I expression; most non-human SIVs, therefore, do not induce immunodeficiency; the HIV-1 nef gene, however, has lost its ability to down-regulate CD3, which results in the immune activation and apoptosis that is characteristic of chronic HIV infection.

Hypergammaglobulinemia

Immunodeficiency with hyper IgM type 2 is caused by a mutation in the Activation-Induced Cytidine Deaminase (AICDA) gene, which is located on the short arm of chromosome 12.

Immunodeficiency with hyper IgM type 5 is caused by a mutation in the Uracil-DNA glycosylase (UNG) gene, which, like AICDA, is located on chromosome 12.

Immune disorder

According to the International Union of Immunological Societies, more than 150 primary immunodeficiency diseases (PIDs) have been characterized.

Lymphoproliferative disorders

In children, the most common is believed to be congenital HIV infection because it is highly associated with acquired immunodeficiency, which often leads to lymphoproliferative disorders.

Myeloperoxidase deficiency

Although MPO deficiency classically presents with immune deficiency (especially candida albicans infections), the majority of individuals with MPO deficiency show no signs of immunodeficiency.

Panacos Pharmaceuticals

As of now, their focus is on Human Immunodeficiency Virus (HIV) anti-infectives, such as Bevirimat.

Vpx

Vpx is a virion-associated protein encoded by human immunodeficiency virus type 2 HIV-2 and most simian immunodeficiency virus (SIV) strains, but that is absent from HIV-1.
