The purpose of this study is to understand why there is a greater risk of thrombosis in patients who have the JAK2 mutation as compared to those with CALR mutations.
This biospecimen study is designed to evaluate the expression levels of TLR 2 and TLR 4 on mononuclear cells in CALR mutation positive MPN participants and compare to JAK2 V617F mutation positive MPN patients and healthy controls. Patients who have MPN with the CALR mutation positive will be approached for interest in participating in this study. A research blood collection will occur at any time during the participant's cancer trajectory after enrollment, during a standard of care blood draw. The participant's demographics, MPN subtype, CALR mutation status, history of thrombosis/other medical history, and current, concomitant medications will be collected once. Clinical data will be collected, including results from the CBC with differential, complete metabolic panel (if available), and PT/PTT/INR (if available) drawn closest to the research blood collection. This study will initially open as a single center study at AHWFBCCC.

RECRUITINGExpression levels of TLR 2 and TLR 4
Percentages of mononuclear cells expressing TLR 2 and TLR 4 will be calculated for each participant.
Time frame: 24 months
Plasma levels of inflammatory cytokines
Presence and levels of inflammatory cytokines, IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, and TNF-α, will be recorded by multiplex Elisa for each participant.
Time frame: 24 months
Plasma levels of inflammatory cytokines following incorporation of TLR ligands
Presence and levels of inflammatory cytokines, IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, and TNF-α, will be calculated for each participant using the in vitro cell culture system.
Time frame: 24 months
History of thrombosis
Determined for each participant as a binary variable indicating whether this participant had history of thrombosis.
Time frame: 24 months
