Researchers: Helpful gut microbes send messages to their hosts’ immune systems

Not to attack. The intestines are full of immune system cells but the helpful microbes manage to avoid the attacks:

Microscopic 3-D images of holdfasts from more than 200 individual bacteria cells revealed small bubbles, or vesicles, emerging from the hook’s sides and tips and budding off within the intestinal wall.

“This was something nobody had noticed before,” though researchers have studied segmented bacteria since the 1960s, Ivanov says. Chemical tests revealed that the vesicles, like delivery packages, contained the bacteria’s antigens — proteins that immune cells use to recognize a foreign body. Usually, antigens stimulate immune cells to attack and kill an invader. But in this case, although T cells were activated, they didn’t go after the bacteria.

“We’re maybe looking at some new biology,” perhaps a new way of communicating, Ivanov says. “I was not expecting to identify a new type of interaction,” … Jeremy Rehm, “How helpful gut microbes send signals that they are friends, not foes” at ScienceNews

Not expecting to identify “a new type of interaction?” But, doubtless, there are many others as well.

So much complex and specified information and yet we are expected to believe it all just happens due to natural selection acting on random mutations (Darwinism). That makes it difficult to anticipate information-based systems.

If the bacterial strategy is clearly identified, they should look for non-helpful microbes that have found a way to copy it (horizontal gene transfer?)

Researchers: First animal cell was not simple; it could “transdifferentiate” From the paper: “… these analyses offer no support for the homology of sponge choanocytes and choanoflagellates, nor for the view that the first multicellular animals were simple balls of cells with limited capacity to differentiate.”
