Scimex: An Australian research team has revealed that the immune cells
enlisted to fight infections in our body are under the control of two
internal ‘clocks’, upending previous theories on how immune responses
are regulated. The team discovered that during an immune response the clocks
allocate a certain amount of time in which the cells can divide, as well
as prescribing the cells’ lifespan. The finding sheds new light on how
the body controls immune responses, as well as explaining how cancers
such as leukaemia and lymphoma maybe caused by errors in this system.
