Glutaminolysis promotes the function of follicular helper T cells in lupus-prone mice.

Glutamine metabolism is essential for T cell activation and functions. The inhibition of glutaminolysis impairs Th17 cell differentiation and alters Th1 cell functions. There is evidence for an active glutaminolysis in the immune cells of lupus patients.

State of the Science: Psychotherapeutic Interventions for Prolonged Grief Disorder.

Prolonged grief disorder (PGD) is a distinct diagnostic entity that has recently garnered considerable attention as it describes an intense, enduring, distressing and disabling bereavement reaction experienced by a small minority of community-based mourners. In recent decades, research has exploded to address how best to treat PGD with different psychotherapeutic interventions. In this state-of-the-science review, the strength of the evidence will be discussed regarding common psychotherapeutic interventions used to treat grief.

The Myosin-V Myo51 and Alpha-Actinin Ain1p Cooperate during Contractile Ring Assembly and Disassembly in Fission Yeast Cytokinesis.

Cytokinesis is driven in part by the constriction of a ring of actin filaments, myosin motors and other proteins. In fission yeast, three myosins contribute to cytokinesis including a Myosin-V Myo51. As Myosin-Vs typically carry cargo along actin filaments, the role of Myo51 in cytokinesis remains unclear.

Lipid droplets are a metabolic vulnerability in melanoma.

Melanoma exhibits numerous transcriptional cell states including neural crest-like cells as well as pigmented melanocytic cells. How these different cell states relate to distinct tumorigenic phenotypes remains unclear. Here, we use a zebrafish melanoma model to identify a transcriptional program linking the melanocytic cell state to a dependence on lipid droplets, the specialized organelle responsible for lipid storage.
