{"doi":"10.14814/phy2.15936","title":"Effect of histamine‐receptor antagonism on the circulating inflammatory cell and cytokine response to exercise: A pilot study","abstract":"Abstract The purpose of this study was to gain insight into histamine's role in the exercise inflammatory response and recovery from exercise. To explore this, young healthy participants ( n = 12) performed 300 eccentric leg extensions under control (Placebo) versus histamine H 1 and H 2 receptor antagonism (Blockade) in a randomized cross‐over study. Circulating leukocytes and cytokines were measured for 72 h after exercise. Circulating leukocytes were elevated at 6 and 12 h after exercise ( p &lt; 0.05) with the peak response being a 44.1 ± 11.7% increase with Blockade versus 13.7 ± 6.6% with Placebo (both p &lt; 0.05 vs. baseline, but also p &lt; 0.05 between Blockade and Placebo). Of the cytokines that were measured, only MCP‐1 was elevated following exercise. The response at 6 h post‐exercise was a 104.0 ± 72.5% increase with Blockade versus 93.1 ± 41.9% with Placebo (both p &lt; 0.05 vs. baseline, p = 0.82 between Blockade and Placebo). The main findings of the present investigation were that taking combined histamine H 1 and H 2 receptor antagonists augmented the magnitude but not the duration of the increase of circulating immune cells following exercise. This suggests histamine is not only exerting a local influence within the skeletal muscle but that it may influence the systemic inflammatory patterns.","journal":"Physiological Reports","year":2024,"id":448320,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":5,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9646,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1266935,"name":"Joshua E.
