17120754-2	2006	We aimed to observe the effects of morphine, fentanyl and tramadol on NF-kappa B and IL-2 from both laboratory and clinical perspective.	Tramadol	58-66	interleukin 2	Homo sapiens	85-89	
16171665-1	2005	STUDY OBJECTIVE: To investigate the effect of tramadol on the production of serum interleukin (IL) 6, IL-10, and IL-2 and soluble (s) IL-2 receptor (R), thereby evaluating its effects on the proinflammatory and anti-inflammatory responses and immune function in cancer patients undergoing conventional pulmonary lobectomy.	Tramadol	46-54	interleukin 2	Homo sapiens	113-117	
16171665-1	2005	STUDY OBJECTIVE: To investigate the effect of tramadol on the production of serum interleukin (IL) 6, IL-10, and IL-2 and soluble (s) IL-2 receptor (R), thereby evaluating its effects on the proinflammatory and anti-inflammatory responses and immune function in cancer patients undergoing conventional pulmonary lobectomy.	Tramadol	46-54	interleukin 2	Homo sapiens	134-138	
16171665-16	2005	As tramadol was associated with increased IL-2 and delayed enhancement of sIL-2R in our study, it may attenuate to some extent an impaired immune response in pulmonary lobectomy.	Tramadol	3-11	interleukin 2	Homo sapiens	42-46	
33385878-7	2021	Besides, tramadol activates natural killer (NK) and T-cells and enhances IL-2 secretion, which produce immune-enhancing effect against SARS-CoV-2.	Tramadol	9-17	interleukin 2	Homo sapiens	73-77
