During hatching, chicks from lines divergently selected for high (HAS) and low (LAS) antibody responses to sheep red blood cells were divided into two groups, each of HAS and LAS, and placed in pens with wood shavings as litter. Feed and water were allowed <jats:italic>ad libitum<\/jats:italic>. Half of the chicks from each line had <jats:italic>Limosilactobacillus reuteri (L. reuteri)<\/jats:italic> inoculated to their drinking water. On day 18, all chicks were given a transcloacal inoculation of 100,000 <jats:italic>H. meleagridis<\/jats:italic> cells. Then, 10\u00a0days later, they were euthanized, followed by collection of tissues from the brain, cecal tonsil, ceca, liver, thymus, and spleen for qPCR analyses of cytokines involved in immunological development. Changes in cytokine expressions were most numerous in the cecal tonsil, ceca, and liver. In the absence of a functional medication for control of histomoniasis, <jats:italic>L. reuteri<\/jats:italic> and\/or its secretory product, reuterin, might serve, in some genetic populations, as a means to reduce the impact of histomoniasis in chickens. The data demonstrate that <jats:italic>L. reuteri<\/jats:italic> treatment had tissue specificity between the two genetic lines, in which the effects were targeted primarily toward the cecal tonsil, ceca, and liver, which are the primary tissue targets of the parasite (<jats:italic>H. meleagridis<\/jats:italic>), as well as the thymus and spleen. However, interactions among main effects reflect that responses to inflammatory markers observed in tissues for one genetic line may not be observed in another.<\/jats:p>","DOI":"10.3389\/fphys.2023.1294560","type":"journal-article","created":{"date-parts":[[2024,1,4]],"date-time":"2024-01-04T04:12:17Z","timestamp":1704341537000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Tissue cytokines in chickens from lines selected for high or low humoral antibody responses, given supplemental Limosilactobacillus reuteri and challenged with Histomonas meleagridis"],"prefix":"10.3389","volume":"14","author":[{"given":"Frank W.","family":"Edens","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul B.","family":"Siegel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert B.","family":"Beckstead","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christa F.","family":"Honaker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dellila","family":"Hodgson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,1,4]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1735","DOI":"10.3390\/vaccines10101735","article-title":"The role of reactive species on innate immunity","volume":"10","author":"Andr\u00e9s","year":"2022","journal-title":"Vaccines"},{"key":"B2","volume-title":"Overview of histomoniasis in poultry","author":"Beckstead","year":"2019"},{"key":"B3","doi-asserted-by":"publisher","first-page":"101656","DOI":"10.1016\/j.psj.2021.101656","article-title":"Evaluation of live-attenuated Histomonas meleagridis isolates as vaccine candidates against wild-type challenge","volume":"101","author":"Beer","year":"2022","journal-title":"Poult.
