A recent article identified a role for alkylglycerol (AKG)-type ether lipids in human breast milk in the regulation of the development of fat tissue in nursing babies (Figure 1). Intriguingly, the lipids affected tissue-resident macrophages in the fat tissue, adipose tissue macrophages (ATMs), not the adipose cells themselves. Using mice, Yu and colleagaues showed that … Read more
Many proteins have multiple roles. Often, the key to effective therapy is specificity. Not only does the treatment need to be specific for a particular physiological target, often a protein, but the therapeutic effects involve only a single function or subset of the target’s functions or needs to affect the target only within a specific … Read more
Better understanding of the molecular mechanisms that control the adaptive immune system will lead to better immunotherapies for cancer patients or patients with other diseases related to inappropriate immune responses. Two of the processes that inhibit T cell function are called immune checkpoint pathways. New research reveals that these pathways involve many cells of the … Read more
