FAM69C functions as a kinase for eIF2α and promotes stress granule assembly.

Stress granules are dynamic cytoplasmic ribonucleoprotein granules that assemble in response to cellular stress. Aberrant formation of stress granules has been linked to neurodegenerative diseases. However, the molecular mechanisms underlying the initiation of stress granules remain elusive.

FAM69C, a kinase critical for synaptic function and memory, is defective in neurodegenerative dementia.

Synapse loss and memory decline are the primary features of neurodegenerative dementia. However, the molecular underpinnings that drive memory loss remain largely unknown. Here, we report that FAM69C is a kinase critically involved in neurodegenerative dementia.

Extracellular vesicles from lung tissue drive bone marrow neutrophil recruitment in inflammation.

Extracellular vesicles (EVs) are single-membrane vesicles that play an essential role in long-range intercellular communications. EV investigation has been explored largely through cell-culture systems, but it remains unclear how physiological EVs exert homeostatic or pathological functions in vivo. Here, we report that lung EVs promote chemotaxis of neutrophils in bone marrow through delivery of double stranded DNA (dsDNA).
