This pattern of cytokine production in patients could be a consequence of an impaired dendritic cell population.enImmunologyFleaAntigenMedicineImmune systemCytokineFlow cytometryPopulationT cellBiologyDifferences in Systemic and Skin Migrating-Specific CD4<sup>+</sup> T Cells in Papular Urticaria by Flea Bitearticle
