NKp44 expression in cells from blood and organs of 9-12 week old piglets and 2-4.5 year old sows. Expression of NKp44 was analyzed on lymphocytes isolated from blood, spleen, bronchial lymph node (BLN), tonsil and lung from 9-12 week old piglets and 2-4.5 year old sows by FCM. (A) Co-expression of NKp44 with CD3, CD8α, CD16 and NKp46 was analyzed. Results are shown for one representative animal (piglet) with frequencies of NKp44+ cells indicated. (B) Frequencies of NKp44+ cells within total lymphocytes of all piglets (PBMC: n=6, organs: n=3) were analyzed. Frequencies of cell populations with mean and standard deviations were as follows: PBMC: 7.3% ± 7.1, spleen: 6.9% ± 3.1, BLN: 2.9% ± 1.2, tonsil: 0.7% ± 0.3, lung: 14.7% ± 4.1. (C) Frequencies of NKp44+ cells within total lymphocytes of all sows (PBMC: n=6, organs: n=3) were analyzed. Frequencies of cell populations with mean and standard deviations were as follows: PBMC: 2.1% ± 1.0, spleen: 1.7% ± 0.6, BLN: 0.7% ± 0.3, tonsil: 0.3% ± 0.1, lung: 4.9% ± 2.5. Means are indicated by red bars.
