Anti-histone antibodies are autoantibodies that are a subset of the anti-nuclear antibody family, which specifically target histone protein subunits or histone complexes. [1] They were first reported by Henry Kunkel , H.R. Holman, and H.R.G. Dreicher in their studies of cellular causes of lupus erythematosus in 1959–60.

This is in contrast to rheumatoid arthritis [6] with systemic sclerosis (scleroderma) [7] because anti-cardiolipin antibodies are present in both conditions, and therefore may tie the two conditions together. Anti-cardiolipin antibodies can be classified in two ways: As IgM, IgG or IgA; As β 2-glycoprotein dependent or independent
Blood type (also called a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
An antibody is made up of two heavy chains and two light chains. The unique variable region allows an antibody to recognize its matching antigen. [73] A B cell identifies pathogens when antibodies on its surface bind to a specific foreign antigen. [74] This antigen/antibody complex is taken up by the B cell and processed by proteolysis into ...
A photomicrograph of Candida albicans showing hyphal outgrowth and other morphological characteristics.. Mannan (oligomannan) is a component of the yeast cell wall.Antibodies to yeast mannans are found at increased frequency in Crohn's disease and ASCA positive Crohn's tend to have lower low levels of mannan-binding lectin. [15]
WASHINGTON (Reuters) -The number of Americans filing new applications for jobless benefits fell more than expected last week, reversing the prior week's jump and suggesting that a gradual labor ...
Anti-centromere antibodies are found in approximately 60% of patients with limited systemic scleroderma and in 15% of those with the diffuse form of scleroderma. The specificity of this test is >98%. Thus, a positive anti-centromere antibody finding is strongly suggestive of limited systemic scleroderma.
