A previous post noted how microbes can help cancers in all stages of their development. Now, it has been found that the one-time microbe now the mitochondria is also vital for cancer to start, to grow, to survive and to metastasize. These microbes and the mitochondria use back and forth communication to help cancers in many ways. This post describes the recent research about mitochondria and its vital relationship to cancer. Mitochondria Joined Forces With Our Cells Two billi

Previous posts have described the very complex pathways that create membranes to surround the entire cell and to build vital cell compartments and well known organelles. A post noted how different types of fatty membranes are built for each organelle with many different complex shapes. These include mitochondria, endoplasmic reticulum, the nucleus and many kinds of vesicles. Vesicles are used for transport, to combat invading microbes and to send information such as with neur

Two thousand years ago Aristotle wrote that cells lining blood vessels determine organs. Recently, he was found correct when capillary cells demonstrated elaborate communication with stem cells and many other cells. Unique capillary cells in each organ have dramatic effects on the life of the cells in that region. With elaborate communication between immune and blood cells, tissue stem cells and neurons, they are the brains of the local region. Now, another cell, called peric

Communication among cells is the basis of all immune and nervous system activity. Research continues to find large vocabularies of signals in different languages—neurotransmitters, cytokines, small RNAs, protein transcription factors, small lipid molecules and glycan sugars. The numbers of signals is growing fantastically with at least 50 neurotransmitters, 100 cytokines, thousands of transcription factors and small RNAs and as yet indefinable large number of ubiquitin tags,

The largest number of brain molecules are lipids (fats). Unique regulation of brain lipids is complex and contributes to many diseases. Surprisingly, it has been found that membrane lipids direct proteins and proteins direct lipids. Previous posts have discussed the importance of lipids in communication between brain cells using vesicles made with fatty membranes. The rapid complex process where lipid covered vesicles transmit neuro transmitters at synapses uses 80% of all o

It is well known that neurons send a variety of intelligent critical signals to other neurons, glia, and immune cells using neurotransmitters, vesicles of several types, cytokines and nanotubes between cells. Elaborate back and forth communication between immune cells uses a wide variety of cytokines, neurotransmitters and vesicles with genetic material. Recently, intelligent decision-making by many other cells was discovered, including epithelial cells lining the intestine a

Dendrites have been considered passive calculators of input signals. In fact, they are extremely dynamic and can produce their own electrical spikes. Dendrites have a vast array of different ways to function when helping to determine the next axon action potential. Recent research has begun to scratch the surface of the complexity of dendrite calculations. A previous post described details about the ever changing and varied dendrite spines and necks with many unique shapes th

It was once thought that to prove the cause of an infection, a microbe is found. The microbe is isolated from the unhealthy person. Later, this infection is reproduced in an otherwise healthy animal by injecting that particular microbe. This approach is described in Koch’s Postulates and was the dogma of microbiology for over a hundred years. However, current research about back and forth elaborate intelligent communication between cells, including microbes, has shown that de

Living among trillions of microbes, it is necessary to determine which are going to cause disease. This is done by recognizing patterns with special receptors on immune cells—pattern recognition receptors or PPRs. Once triggered, receptors activate powerful mechanisms to cause inflammation that is life saving but, also, can attack our own cells with chronic inflammation and autoimmune diseases. In fact, as with every other critical aspect of physiology, pattern recognition re
