PSG released from various grass pollen species are bound and phagocytosed by AM

Rye grass1.0 ± 0.031.0 ± 0.01
Bermuda grass0.8 ± 0.030.9 ± 0.01
Timothy grass5.5 ± 0.440.9 ± 0.02
Bluegrass0.8 ± 0.090.7 ± 0.01
Orchard grass4.1 ± 0.671.1 ± 0.03
Johnson grass4.1 ± 0.011.1 ± 0.03

Canary grass0.8 ± 0.081.1 ± 0.03
  • a The relative PSG release was calculated by comparing the total number of PSG released from a fixed quantity of each pollen species (50 mg in 10 ml water) to that released by rye grass. Data are presented as means ± SEM (n = 3).

  • b The relative level of PSG binding and phagocytosis was calculated by comparing the nMFI of AM resulting from a 4-h incubation with FITC-PSG (MOI, 20) from each pollen species to that resulting from rye grass FITC-PSG. Data are presented as means ± SEM (n = 3).
