Measles virus (MV) induces profound suppression of the immune response during and for weeks after acute infection. On the other hand, virus-specific immune responses that mediate viral clearance and confer long-lasting immunity are efficiently generated. To investigate this paradox, we studied the immune responses to MV using a monkey model of acute measles. Cynomolgus monkeys were experimentally infected with wild-type MV (MV-HL) and showed marked leukopenia associated with a steady reduction in CD4+ T cell numbers for 18 days post-inoculation. Transient expression of interferon and IL-6 were observed in the serum between 4 and 6 days post-inoculation, and IL-10 levels increased after 11 days post-inoculation. Interestingly, IL-8 showed a three-peak increase that correlated with an increase in neutrophils. A non-human primate model of measles allows the early immune response against MV to be studied in more detail.

D008457 Measles A highly contagious infectious disease caused by MORBILLIVIRUS, common among children but also seen in the nonimmune of any age, in which the virus enters the respiratory tract via droplet nuclei and multiplies in the epithelial cells, spreading throughout the MONONUCLEAR PHAGOCYTE SYSTEM. Rubeola

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D016176 T-Lymphocyte Subsets A classification of T-lymphocytes, especially into helper/inducer, suppressor/effector, and cytotoxic subsets, based on structurally or functionally different populations of cells.

D016207 Cytokines Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner. Cytokine
