Research Interests
Dr. Gunning's current research emphasis involves the study of bleeding diathesis specifically related to platelet dysfunction.ÌýÌýHe has evaluated patients with prolonged bleeding times and/or a history of bleeding including individuals that bruise easily and women with menorrhagia for more than 25 years.ÌýÌýWhen tested for von Willebrand disease, these individuals are usually found to have normal aggregation responses or have a slight abnormality in response to epinephrine but not to ristocetin and are therefore, often a diagnostic enigma.ÌýÌýHis research utilizes a transmission electron microscope and computer analysis of platelets obtained from peripheral blood to determine the number and volume of delta granules (dense bodies) that contain important substances used for the effective coagulation of blood.Ìý
Dr. Gunning has a number of collaborators throughout the country and the preliminary results of these studies suggests that delta granule storage pool deficiencies (δ-SPD) may be a significant etiology of bleeding diathesis, especially in the case of menorrhagia.ÌýÌýIn addition, he has discovered a significant correlation with postural orthostatic tachycardia syndrome (POTS, a type of syncope) and δ-SPD.ÌýÌýHe has recently reported that POTS has a number of adrenergic and muscarinic receptor antibodies that suggest POTS is an autoimmune disease.ÌýÌýHe has also reported that POTS patients have elevations of a number of innate immune system cytokines and chemokines and is actively.ÌýÌýHe recently gave an invited presentation of unpublished data at Experimental Biology 2021.
