Abstract
In the human, chemokines represent a structurally related family of more than forty cytokines which act on distinct subsets of leukocytes via specific G protein-coupled receptors expressed on the cell surface. The induction of select repertoires of chemokines following exposure to allergen provides a biological basis for the selective leukocyte recruitment, observed both clinically and experimentally. The chemokine receptor CCR3 is expressed on the cell surface of eosinophils, Th2 lymphocytes, basophils and mast cells and binds the Eotaxin family of chemokines (CCL11, CCL24 and CCL26), whose production is upregulated following allergen challenge. Once recruited, eosinophils are a source of growth factors associated with tissue repair and remodelling and also have the ability to induce tissue damage, a capacity that extends from their traditional role in protecting the host against parasitic worms. Thus, impairment of their recruitment by selective blockade of the CCR3:eotaxin axis represents an attractive target for the therapeutic treatment of asthma. In this review, we will examine recent developments in the field and highlight the roles of other chemokine:chemokine receptor axes implicated in leukocyte recruitment during allergic inflammation.

New drug therapy for eye diseases
Eyesight is one of the most critical senses, accounting for over 80% of our perceptions. Our quality of life might be significantly affected by eye disease, including glaucoma, diabetic retinopathy, dry eye, etc. Although the development of microinvasive ocular surgery reduces surgical complications and improves overall outcomes, medication therapy is ...read more
