Cytokines in the modulation of eosinophilia.
نویسندگان
چکیده
In this review we discuss our recently results showing interleukin 5 (IL-5) involvement in eosinophil migration and in the maintenance of eosinophilia in blood, bone marrow, lung and peritoneal cavity, in a visceral larva migrans syndrome model using guinea-pigs infected with Toxocara canis. We also describe the sequential release of TNF-alpha and IL-8 during the course of infection. Finally we propose a biological role for IL-5, at least in our model, as a modulator of IL-8 release and secretion.

The thalamus is a central element for the generation of rhythmic oscillatory activity under physiological and pathophysiological conditions. Especially slow oscillations in the delta and theta frequency band which normally occur during slow-wave sleep are associated with a number of neuropsychiatric conditions if they occur during wakefulness and may be the basis for the generation of character...
متن کاملCYTOKINE AND GROWTH FACTOR MODULATION OF CELL CYCLE EVENTS IN HUMAN MELANOMA CELL LINES
Cytokines influence cell cycle events, which in some but not all instances can be associated with melanoma progression. Analysis of the G0/G 1 and S phase fractions of the cell cycle was used to assay the proliferative or inhibitory activity of cytokines against ten human melanoma cell lines, including pairs of cell lines derived from primary and metastatic tissue of individual patients. Cy...
متن کاملGhrelin Exerts Analgesic Effects through Modulation of IL-10 and TGF-β Levels in a Rat Model of Inflammatory Pain
Background: Ghrelin is a peptide with attenuating effect on inflammatory pain. Both anti- and pro-inflammatory mediators have a role in the nociception and development of pain and hyperalgesia. IL-10 and TGF-β are anti-inflammatory cytokines and inhibit the expression of pro-inflammatory cytokines related to peripheral and central inflammatory pain. In this study, the effects of i.p. injec...
