Insall R. Dispatch. Dictyostelium chemotaxis: fascism through the back door? Curr Biol. 2003 Apr 29;13(9):R353-4. doi: 10.1016/s0960-9822(03)00274-4. PMID: 12725750.
Abstract Aggregating Dictyostelium cells secrete cyclic AMP to attract their neighbours by chemotaxis. It has now been shown that adenylyl cyclase is enriched in the rear of cells, and this localisation is required for normal aggregation. Dictyostelium discoideum cells undergo a major lifestyle change when they get hungry. They grow as unicellular amoebas, but when food starts to…

Deficiency of Adenosine deaminase 2 (DADA2)
Deficiency of Adenosine deaminase 2 (DADA2) is a monogenic disease associated with systemic inflammation and vasculopathy that affects a wide variety of organs in different patients. As a result, it is hard to characterize a patient with this disorder. Manifestations of the disease include but are not limited to recurrent fever, livedoid rash (reticularis or racemosa), various cytopenias, stroke, immunodeficiency, and bone marrow failure. Symptoms often onset during…

Adenosine deaminase deficiency (ADA deficiency) was discovered in 1972 and recognized as the first immunodeficiency disorder
Adenosine deaminase deficiency (ADA deficiency) is a metabolic disorder that causes immunodeficiency. It is caused by mutations in the ADA gene. It accounts for about 10–15% of all cases of autosomal recessive forms of severe combined immunodeficiency (SCID) among non-inbred populations. ADA deficiency can present in infancy, childhood, adolescence, or adulthood. Age of onset and severity is related to some 29 known genotypes associated with the disorder. It occurs…

Adenosine
Adenosine (symbol A) is an organic compound that occurs widely in nature in the form of diverse derivatives. The molecule consists of an adenine attached to a ribose via a β-N9–glycosidic bond. Adenosine is one of the four nucleoside building blocks of RNA (and its derivative deoxyadenosine is a building block of DNA), which are essential for all life. Its derivatives include the energy carriers adenosine mono-, di-, and triphosphate, also…
