People with celiac disease usually have a certain type of cell surface receptor that helps set off the immune reaction.
Erbitux and Vectibix are antibodies that bind to receptors on the cell surface called EGF and blocks signals that turn kras on.
So the idea is to use a second pill to get the CFTR protein up to the cell surface so Kalydeco can work.
FORBES: The Best Argument That Vertex's CF Drug Combination Works
Now entering human trials, it blocks a newly discovered receptor known as H3, the third in a family of crucial cell-surface proteins that receive messages from the hormone histamine.
Like a key in a lock, EGF binds to a receptor on a cell's surface, sending off a signal to the cell to divide, grow and die.
The antibodies bind to the CTLA-4, found on a cell's surface, and shut off the brake.
This gets stuck on the cell's surface and then reacts with a stain that is added to the sample.
The HIV virus reproduces with a cell, then virus particles bud off that cell's surface to infect other cells in the body.
HINT, crops up in 11 different genes for receptor proteins that sit on a cell's surface waiting for messenger molecules from other cells.
ECONOMIST: The first complete DNA sequence of an animal is now in the bag
"Essentially we know the ZIP code of vessels within a certain tissue, we can program the address on the surface of the cell, " he said.
It sits inside the surface of a cell and springs into action when signaled by other cells, activating proteins that temporarily boost the connection between two nerve cells.
The Novartis drug suppresses a protein called MTOR (mammalian target of rapamycin), which receives incoming growth signals from the surface of the cell and directs them to grow fatter, a necessary step before cell division.
To remedy this problem, Kylie Catchpole of the Australian National University in Canberra and Albert Polman of the Institute for Atomic and Molecular Physics in Amsterdam have been trying to redirect the light that falls onto the surface of a cell in such a way that all colours are efficiently absorbed.
And, as a bonus, it is the protein that locks on to the surface of a host cell before the virus enters it.
Pyron uses an acrylic concentrating lens, which focuses the equivalent of the light from 6, 500 suns on a small optical device, which then spreads it across the surface of the solar cell.
Dr Kamat and his team covered the surface of an experimental cell made of cadmium sulphide, zinc oxide and titanium dioxide with nanotubes, so that the tubes stuck up from the surface like hairs.
Even more surprisingly, they found that each receptor, located on the surface of a particular cell, is unique, and when activated by an odorant, triggers the cell to send an electrical signal to the brain.
The researchers in this study examined the geometric structure and behaviour of one of the rotavirus's surface proteins, called VP4, which plays a key role in binding on to the surface of a target cell, and breaking through its membrane.
However, before the alarm can be sounded in this way, proteins on the surface of the antigen-presenting cell and the T cell must bind together in what is called a cellular handshake.
In a process called LED photomodulation, the light stimulates the production of cell-producing proteins under the skin's surface.
By integrating both the touch sensors and the solar cell layers into the same stack-up, surface area on the portable device may be conserved.
FORBES: Patent Approval Paves Way For Apple To Fire Up Solar Powered iPhone
Thus a cancer cell stupid enough to be carrying this protein on its surface is going to have a difficult battle on its hands.
FORBES: Exciting New Breast Cancer Drug Poised to Break the Bank?
Using tumor samples from wo-men with breast cancer, he used a gadget called a cell sorter to sift through dozens of different proteins on the surface of breast cancer cells, searching for patterns that might identify stem cells.
T-cell, so that it would recognise the molecules found on the outer surface of melanomas.
The gene produces a molecular sensor on the T cell that is designed to latch on to a telltale protein on the surface of that specific type of cancer.
This will be useful because the location and activity of receptor proteins on surface membranes can be a matter of life and death for a cell or a virus.
To enter a cell, a virus often latches first on to one of the proteins on its surface.
