"CCL2 is a small cell-signaling protein that recruits immune cells to sites of inflammation. CCR2 is CCL2’s receptor. Together, CCL2 and CCR2 create an inflammatory and immune-suppressive microenvironment, which promotes tumor growth and progression and induces resistance to anticancer drugs. A recent review highlights research on the therapeutic potential of targeting this so-called “CCL2-CCR axis”. Circulating levels of CCL2 are particularly elevated in individuals with obesity. Studies on men with prostate cancer suggest that inhibiting CCL2 signaling can significantly inhibit tumor growth and invasion. More work is needed to differentiate natural CCL2 levels in patients from tumor-derived CCL2 involved in the formation and spread of tumors, which could lead to new ways of attacking cancer and cancer resistance..."

"Once considered little more than “cell dust”, exosomes are receiving much deserved attention from the research community. Exosomes are tiny sacs whose job includes clearing the cell of certain lipids, proteins, and nucleic acids. But researchers are learning that exosomes are also crucial to signaling and communication between cells. A new review explores various ways exosomes help coordinate the metabolism of lipids in the body. Some of the most promising research describes what happens when exosomes’ ability to synthesize, transport, and degrade lipids is compromised. In some cases, that can lead to disorders such as atherosclerosis, cancer, obesity, and Alzheimer’s disease. Understanding how exosomes orchestrate metabolic activities could clue researchers in on new ways to diagnose and treat related diseases..."

"Mesenchymal stromal cells, or MSCs, regulate many functions critical to maintaining organ health. They do so by sending and receiving biochemical signals across short and long distances. How this signaling function is altered by disease, however, remains unclear. In a recent study, researchers examined how obesity in mice affects the signaling functions of MSCs from fat tissue and bone marrow. The proteins secreted by MSCs in mice fed a normal diet play a role in detoxification activity in response to toxic substances and drugs. They are also involved in bone, cartilage and fat development. Further analyses revealed that mouse MSCs participate in two major signaling pathways: platelet degranulation, where signaling molecules wrapped up in granules are deployed to regulate blood clotting and inflammation; and the insulin-like growth factor pathway, which regulates cell proliferation, survival, and metabolism. Comparing proteins secreted by MSCs in normal vs. obese mice revealed key differences..."
