"I think the best athletes use it": Masculinities and self-compassion among men varsity athletes.

We examined how men varsity athletes' embodiments of masculinities shaped their perceptions and experiences of self-compassion to manage sport-related challenges. Two semi-structured interviews were conducted with 11 men varsity athletes (20 interviews total). Vignettes depiciting athletes low and high in self-compassion were used as talk elicitation tools during interviews.

Activation of regulatory T cells triggers specific changes in glycosylation associated with Siglec-1-dependent inflammatory responses.

: Siglec-1 is a macrophage lectin-like receptor that mediates sialic acid-dependent cellular interactions. Its upregulation on macrophages in autoimmune disease was shown previously to promote inflammation through suppressing the expansion of regulatory T cells (Tregs). Here we investigate the molecular basis for Siglec-1 binding to Tregs using -induced cells as a model system.
