Cxcr2 Is Required for Neutrophil Response to Cxcl8a and Pseudomonas aeruginosa Infection
(A) Representative imaging of the otic vesicle (white dotted outline) 2 hr after injection with supernatant from HEK cells overexpressing zebrafish Cxcl8a or control supernatant. Supernatant was injected into the otic vesicle of 3 dpf Tg(mpx:Dendra) WT or Cxcr2−/− larvae (neutrophils in green).
(B) Number of neutrophils in the otic vesicle of Cxcl8a or control supernatant injected larvae (n = 59 WT and 58 mutant [Ctrl] and 56 WT and 54 mutant [zCxcl8a]).
(C) Neutrophil fold change response to Cxcl8a over control supernatant.
(D) Representative imaging of the otic vesicle (white dotted outline) 2 hr after injection with P. aeruginosa in WT or Cxcr2 mutant Tg(mpx:Dendra) larvae.
(E) Number of neutrophils in the otic vesicle of P. aeruginosa or vehicle-injected larvae (n = 62 WT and 73 mutant [PBS] and 76 WT and 76 mutant [P. aeruginosa]).
(F) Neutrophil fold change response to P. aeruginosa over PBS control. ∗p < 0.05.
