Immune megakaryocytes, PD1 deletions in CTCL, and COVID-19 vaccine and VITT

In this week’s episode, we’ll review a study providing new insights on megakaryocyte diversity and function, including a unique subpopulation that may act as immune cells. Next, we’ll review research that intriguingly reveals a putative role for the PD1 gene in cutaneous T-cell lymphoma. Lastly, we’ll conclude with a report demonstrating a lack of cross-reaction between the antibodies that cause vaccine-induced thrombocytopenia and thrombosis, and the COVID-19 spike protein.
