Mitochondria Help Cancers Grow

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…

The First Virus Communication Signals

One of the first discoveries about the unusual behavior and cognitive abilities of bacteria was a signal put out by many of the members of a community to make a group decision. This “quorum sensing” signal stimulates collaborative attacks and migration by sensing if there are enough providing signals to carry out the…

How Do Bacteria Help Cancer

Cancers are a community of cells that engage in continual conversations to help their cells thrive, to expand to new locations, and to fight off attacks from immune cells, microbes, and other cells. Bacteria are another community of cells that constantly talk among themselves for group activity such as finding food,…

Each Cell Has A Clock

For many years there was a consensus that most organisms have a circadian clock. In humans it was considered to be directed centrally by the master clock in the brain region suprachiasmatic nucleus (SCN). This clock appears to be involved in directing essential physiological processes throughout the body including…

Complex Cellular Conversations about Food Allergies

It is quite remarkable that the immune system can deal with an almost infinite number of different molecules and not have more disasters. In creating antibodies and receptors, immune cells are able to respond to newly synthesized molecules that have never been seen in nature before. Equally remarkable is the response to…

Pain from Cells that Are Not Neurons

Recent research on pain shows a very surprising result. A new type of neuroplasticity has been discovered where “pain” teaches parts of the brain to experience more pain. Most surprising is that neurons are not involved—but rather brain glial cells, cancer cells, microbes, and immune cells. One recent result shows…

Update on Microbes Affecting the Brain

Recent posts had already shown that gut microbe signaling with the human brain can have positive and negative effects on anxiety, stress, depression, obesity and degenerative illness. This occurs by neurotransmitters secreted into the blood, gut neuron stimulation, microbe travel into the brain, and immune cells…

Special Relationship of Viruses and Endoplasmic Reticulum

It is quite remarkable how much viruses can accomplish with a very small number of genes and a handful of proteins. Previous posts have described the very elaborate lifestyle of HIV with only 9 genes, and Ebola with only 7 genes. Somehow, viruses are able to manipulate vast cellular machinery including organelles much…

Are Fungus the Dominant Life Form

Bacteria and viruses exhibit communication and almost endless creativity and variation. We have no real idea just how many species there are. Bacteria and viruses have dramatic effects on the ecology of every part of the earth. Because of this, they have been considered by some to be the dominant life form. An increasing…

Inflammasomes Are Large Complex Signaling Platforms

FEATURE Protein molecule for Complex Neuron Machinery

Many large proteins combine to form a signaling platform that orchestrates many varied types of inflammation. Irregularities in any of the proteins of this complex structure can produce devastating diseases, including cancer and autoimmune, metabolic and brain diseases. Inflammation can be caused by toxins, trauma and many…

Viruses evade DNA RNA Sensors

Some think viruses are not alive. It is, therefore, very surprising that they can evade elaborate cellular mechanisms used to find and destroy them. Search and destroy mechanisms of the cell and counter attacks from viruses are very complex. Cells use many sensors to find DNA and RNA that is not where it is supposed to be….

Biofilm Geo Politics

Biofilms are major causes of severe infections because microbes are able to protect themselves in a tough 3-D matrix that is difficult for the cell to attack. Until recently, it was thought that one dangerous microbe builds a biofilm. As has been found with most microbe activities, their strength derives from back and…

Microbe Geo Politics in the Gut

With trillions of microbes comprising thousands of species or more, it has been impossible to fully study their composition or exact locations in the gut. Even more complex is their back and forth chatter between multiple Kingdoms such as bacteria, viruses, archaea, fungi, and eukaryote human cells in the lining and immune…

The Politics of Gut Microbe Kingdoms

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…

Vast Complexity of Immune Pattern Recognition Receptors

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.

Many New Microbe Molecules Discovered in Humans

Inside of each of us, there are ten times as many bacteria and 100 times as many viruses as our own cells. This means we have 300 times more DNA from microbes inside of us than our own DNA (the total DNA has been called the hologenome- see post). Microbe DNA is not quiet, but is producing large amounts of molecules that…
