After the synthetic middle people of the intense reaction die down, late-stage reactions can frequently happen. This is because of the relocation of different leukocytes like neutrophils, lymphocytes, eosinophils, and macrophages to the underlying site. The response is normally seen 2-24 hours after the first response. Cytokines from pole cells might assume a part in the determination of long haul impacts. Late-stage reactions found in asthma are marginally not quite the same as those seen in other unfavorably susceptible reactions, in spite of the fact that they are as yet brought about by arrival of go betweens from eosinophils and are as yet reliant upon action of TH2 cells.
