Lupus erythematosus may manifest as systemic disease or in a purely cutaneous form also known as incomplete lupus erythematosus. Lupus has four main types: [citation needed] systemic; discoid; drug-induced; neonatal; Of these, systemic lupus erythematosus (also known as SLE) is the most common and serious form.
Research conducted in the 1920s and 1930s led to the first detailed pathologic descriptions of lupus and demonstrated how the disease affected the kidney, heart, and lung tissue. [165] A breakthrough was made in 1948 with the discovery of the LE cell (the lupus erythematosus cell—a misnomer, as it occurs with other diseases as well).
Scientists have long suspected that a person’s genetics or hormones may predispose them to lupus, and that the disease may be triggered by environmental factors like a previous viral infection ...
Childhood-onset systemic lupus erythematosus (i.e., cSLE), also termed juvenile-onset systemic lupus erythematosus, juvenile systemic lupus erythematosus, and pediatric systemic lupus erythematosus, is a form of the chronic inflammatory and autoimmune disease, systemic lupus erythematosus (i.e., SLE), that develops in individuals up to 18 years old. [1]
The disease impacts about 1.5 million Americans, but women are nine times more likely to develop lupus than men. And the cause of lupus has largely remained a mystery—until now.
Levels of DNMT1 is partly regulated by the ERK signaling pathway in the body. In patients with SLE, ERK activity has been found to be reduced in lupus CD4+ T-cells. When ERK activity is suppressed, it causes there to be a reduction in DNMT1 expression and DNA hypomethylation levels increases.
Undifferentiated connective tissue disease (UCTD) (also known as latent lupus or incomplete lupus [1]) is a disease in which the connective tissues are targeted by the immune system. It is a serological and clinical manifestation of an autoimmune disease .
The amount of mitochondria per cell also varies by cell type, with some examples being: Erythrocytes: 0 mitochondria per cell. [1] Lymphocytes: 3 mitochondria per cell. [7] Egg cell: Mature metaphase II egg cells can contain 100,000 mitochondria, and 50,000–1,500,000 copies of the mitochondrial genome (corresponding to up to 90% of the egg ...
