    as inhaled cigarette smoke induce and activate macrophages, neutrophils, natural killer cells, which belong to the innate immune system as well as epithelial cells in lungs. Activation of these cells causes release of substances called chemotactic cells, for instance, C‑chemokine ligand 2 (CCL2) that leads to attracting inflammatory cells such as monocytes. In addition, these macrophages and epithelial cells release multiple chemokines, including fibroblast growth factor (FGF) that causes proliferation

    very sensitive. The airways are tubes that carry air into and out of a person’s lungs. When theses airways react to certain stimuli, the muscles around them tighten, narrowing the airways and causing less air to flow to the lungs. When this occurs, cells in the airways can also make more mucus than usual, which causes a sticky, thick liquid to be excreted and further narrows the swollen airways. This process is all caused when the person inhales certain substances that aggravate the sensitive airways

    in the development of allergies: immunoglobulin E (IgE), mast cells and histamine. IgE is a specific type of antibody that has a significant role in the development of allergies; IgE is able to bind to both allergens and to mast cells, cells that mediate inflammatory responses such as hypersensitivity and allergic reactions (3). Once IgE binds to an allergen, the allergen releases T cells to stimulate B cells, developing into plasma cells that produce and release more antibodies (4). Once
