Changing the order in which presynaptic and postsynaptic cells are repeatedly activated can change what a mammalian visual cortex neuron communicates to downstream neurons.
Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.
A transmembrane protein uses distinct mechanisms to regulate the movement of specific toll-like receptors-key immune system components involved in detecting pathogens-to their final locations inside cells.
A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.
The ability to share resources for the benefit of all members of a group may have driven ancient organisms to evolve from a unicellular to a multicellular state.
Identifying and treating those groups of individuals that are most likely to transmit the malaria parasite to mosquitoes could help to control the spread of the disease.
Goblet cells secrete mucins—which are key components of mucus—in a process that is regulated by calcium ions, which enter the goblet cells via a mechanism involving a channel protein called TRPM5.
A compound that prevents stressors such as UV light and viral infection from downregulating protein synthesis inside cells improves memory performance in mice.
Genetic and electrophysiological experiments reveal that a gene called MCU encodes the ion channel pore that allows calcium ions to cross the inner mitochondrial membrane.
