[ 89 ] Possible consequences of measles virus infection include laryngotracheobronchitis , sensorineural hearing loss , [ 51 ] and—in about 1 in 10,000 to 1 in 300,000 cases [ 90 ] — panencephalitis , which is usually ...
Purified cell wall components of mycobacteria activate mainly TLR2 and also TLR4. Lipomannan and lipoarabinomannan are strong immunomodulatory lipoglycans. [ 20 ] TLR2 with association of TLR1 can recognize cell wall lipoprotein antigens from Mycobacterium tuberculosis , which also induce production of cytokines by macrophages . [ 21 ]
Langerhans cell is represented by a yellow oval; blue arrows correspond to is_a relations, and orange arrows correspond to develops_from relations. Only a subset of Langerhans cell parent types are included in the figure. [1] A Langerhans cell (LC) is a tissue-resident macrophage of the skin [2] once thought to be a resident dendritic cell. [3]
