[Advances of studies on the occurrence of the upper respiratory disease correlative with immunity and tobacco].

SummaryTobacco smoke exposure has obvious and complex effects on the immune system of the human upper respiratory tract, including pro-inflammatory and anti-immune effects. Exposure to tobacco smoke is closely related to the occurrence and development of allergic rhinitis, the common rhinitis and sinusitis. The innate immune system is influenced by tobacco smoking through its effects on the respiratory mucosa and its adjuncts, natural killer cells, dendritic cells, neutrophils and innate immune receptors. Cigarette smoke can also affect the humoral immunity and cellular immunity, altering the acquired immune condition of the upper respiratory tract. Tobacco smoke exposure promotes the occurrence and development of the upper respiratory tract infectious diseases and allergic diseases by changing the composition of microflora in the upper respiratory tract.
