I am excited to share the work that composed the majority of my PhD, now published in #CellMolImmunol

(2/13) We studied the glycome of human and murine thymocytes and asked whether a N-glycosylation blockade would affect murine T cell development and susceptibility to disease

(3/13) It has been known for decades that mature thymocytes possess some glycans that immature ones do not. However, research on the glycome of thymocytes and how it regulates developmental checkpoints has only received episodic, but seminal, attention

(4/13) Ever since Peter Nowell discovered that a plant lectin could stimulate T cells in vitro, it has been clear that the glycome should play a major role on regulating T cell activity and function

(5/13) In a seminal paper, the Demetriou´s lab showed that the degree of N-glycan branching of thymocytes tuned the affinity range for TCR-based selection

(6/13) In our work we show that the glycocalyx composition is dynamic across developing thymocytes, both in human and mice, using plant lectins

(7/13) In addition, we analyzed available scRNA-seq data from human and murine thymocytes and observed that key glycogenes’ expression levels displayed the same dynamic developmental features as the lectin binding levels
