Increase of chemokine levels in sputum precedes exacerbation of acute asthma attacks

Journal of Leukocyte Biology

Abstract

Basophils and eosinophils can be activated in vitro by several chemokines such as RANTES, monocyte chemotactic and activating factor (MCAF/MCP-1), macrophage inflammatory peptide-1 alpha (MIP-1 alpha), and interleukin-8 (IL-8). To explore the clinical relevance of the in vitro observations, we measured here the concentrations of these chemokines in sputa from asthmatic patients during acute attacks. Before the onset of a late-phase exacerbation, sputum MCAF/MCP-1, MIP-1 alpha, and IL-8 levels transiently but markedly increased from the basal levels in all of the patients with exacerbation, whereas the sputum levels of these chemokines remained unchanged during the course in the patients without a late-phase exacerbation. These results suggest the involvement of these chemokines in the late-phase exacerbation of asthma.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Basophils

Basophils are myeloid cells with a high affinity IgE receptor and is involved in inflammatory responses during allergy. Discover the latest research on Basophils here.
