Sysyem goal? Restore balance. Systm cells are segregated into two major types: Psychotherapy as a treatment for depression and adaptive. Innate cells are the first responders. They recognize a threat, mount an Imkune and call for help.

This could be especially important in tumor microenvironments, which can be nutritional deserts. Kaech wants to understand, and ultimately control, these mechanisms to boost the immune response against cancer. DECODING INTERNAL CHIT CHAT. Immune research has been focused on external factors—the pathogens and molecular signals that kick the immune response into high gear.
But what about internal signaling? There are two ways to investigate this. How are these molecules in the right place at the right time to even have these conversations?
Associate Professor Björn Lillemeier studies both. So how do key signaling proteins know where to be and when? These are difficult questions to answer because the scales are so small. The molecules the lab is tracking are around 2 nanometers and roam an area between 50 and nanometers—a space times smaller than the width of a human hair.
Traditional light microscopy can visualize objects as small as to nanometers, hardly suitable for such high-resolution studies. If researchers try to image a nanometer area, light sources that come too close together in this case proteins blur into indistinguishable blobs, like seeing a large city from space at night.
The lab solved this problem by imaging individual proteins. The lab has embraced leading-edge super-resolution microscopy, which allows them to image areas as small as 25 nanometers.
They take thousands of images to painstakingly piece together the larger picture. Lillemeier combines this approach with traditional biochemistry and cell biology, mutating proteins to see how the changes alter T cell function.
These efforts could have a major impact. Normal tissue turns on a T cell protein called PD-1 to counterbalance the activation of T cells.
Tumors use the same trick to avoid immune attack. Cancer immunotherapies called checkpoint inhibitors turn off the enzyme to take the brakes off T cells and coax them to attack tumors.
But this is a binary approach and only works for around 20 percent of patients with specific cancers, such as lung and melanoma. Eventually, he wants to provide more nuanced strategies to influence T cells.
Being able to exert such precise control could open more patients to immunotherapies and mitigate side effects. Greg Lemke, a professor in the Molecular Neurobiology Laboratory, studies TAM receptors Tyro3, Axl, and Merwhich are found on macrophages and other cells and shut down an immune response after it has completed its work.
TAM receptors are also in charge of detecting dead cells. Millions of cells die each second—more than a hundred billion a day. With reduced TAM signaling, they stop engulfing dead cells, kind of like a garbage strike, causing a cascade of problems. It starts with chronic inflammation.
Then, because the immune system stays ramped up, the body can slip into an autoimmune response. The Lemke lab has shown that TAM signaling is a lot more important than previously thought. Just as tumors can turn off T cells, influenza, West Nile and other viruses can activate TAM receptors to evade immune surveillance.
The lab also found that losing the Mer receptor in retinal cells can lead to blindness. Dysfunctional TAM signaling also generates adverse consequences for microglia, the macrophages in the central nervous system. Without TAM-directed signals, microglia also stop disposing of dead cells, which contributes to, and exacerbates, neurodegenerative disease.
TAM receptors are one of many mechanisms designed to modulate the immune system. Tregs, which keep T cells from overreacting, are another way to dial down the immune response. In some ways, they are a firewall against autoimmune disease.
Tregs suppress other immune cells from attacking. Tregs make up around 10 percent of all T cells and could hold the key to immune system homeostasis.
Making them more suppressive could help researchers address autoimmune conditions. Making them less suppressive could promote the immune response against cancer. For Zheng, the quest to better understand them begins with a protein called Foxp3, which is essential for Treg development.
The Zheng lab has been focused on understanding the role Foxp3 plays in Treg development. That means identifying hundreds of interrelated genes—the ones that control Foxp3 and the ones that it controls. Through this detailed process, the lab has identified anomalies that can transform Tregs into cytotoxic T cells, generating autoimmunity in animal models.
Zheng believes these and other findings could help lead to Treg-based therapies. It could be a very powerful tool. WHAT BACTERIA CAN TEACH US. Learning how various immune cells respond to pathogens—both individually and collaboratively—could give us better tools to manage infections.
But the body has other mechanisms to deal with hostile microbes and the damage they cause. Associate Professor Janelle Ayres has a unique way to learn about these systems—by querying the pathogens themselves.
Ayres is looking for alternatives to vaccines and antibiotics. Vaccines are not available for all viruses, and bacteria are developing resistance to our most powerful therapies.
While many people believe the solution is new antibiotics, evolution is an unstoppable force. Sooner or later, microbes will develop resistance to the latest penicillin reboot. On the other hand, what if evolution could be our friend? Around ten years ago, Ayres discovered the cooperative defense system, a collection of mechanisms that prevent physiological damage during infection.
The system promotes health without killing the microbe and, in fact, is often initiated by microbes themselves. They need to keep their host healthy enough to keep hosting. But Salmonella has its ways.

Rather than killing the pathogens, Ayres believes we can exploit cooperative defense mechanisms to protect people from collateral damage from Salmonella, sepsis and other conditions.
Successful cancer immunotherapies are lighting the way for researchers to really deconstruct immunity. This work will eventually lead to new treatments for cancer, infectious diseases and autoimmune conditions, but it also illustrates how biology functions on the deepest levels.
Thus, our immune system has the potential to interact with every cell type in our body and intersects with virtually every biological process. That makes it an important crossroad in science and an incredible opportunity for collaboration. Email Address. edu permission to email you.
Whether this decrease in thymus function explains the drop in T cells or whether other changes play a role is not fully understood. Others are interested in whether the bone marrow becomes less efficient at producing the stem cells that give rise to the cells of the immune system.
A reduction in immune response to infections has been demonstrated by older people's response to vaccines. For example, studies of influenza vaccines have shown that for people over age 65, the vaccine is less effective compared to healthy children over age 2.
But despite the reduction in efficacy, vaccinations for influenza and S. pneumoniae have significantly lowered the rates of sickness and death in older people when compared with no vaccination.
There appears to be a connection between nutrition and immunity in the elderly. A form of malnutrition that is surprisingly common even in affluent countries is known as "micronutrient malnutrition.
Older people tend to eat less and often have less variety in their diets. One important question is whether dietary supplements may help older people maintain a healthier immune system. Older people should discuss this question with their doctor.
Like any fighting force, the immune system army marches on its stomach. Healthy immune system warriors need good, regular nourishment. Scientists have long recognized that people who live in poverty and are malnourished are more vulnerable to infectious diseases.
For example, researchers don't know whether any particular dietary factors, such as processed foods or high simple sugar intake, will have adversely affect immune function. There are still relatively few studies of the effects of nutrition on the immune system of humans.
There is some evidence that various micronutrient deficiencies — for example, deficiencies of zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, and E — alter immune responses in animals, as measured in the test tube.
However, the impact of these immune system changes on the health of animals is less clear, and the effect of similar deficiencies on the human immune response has yet to be assessed.
So, what can you do? If you suspect your diet is not providing you with all your micronutrient needs — maybe, for instance, you don't like vegetables — taking a daily multivitamin and mineral supplement may bring other health benefits, beyond any possibly beneficial effects on the immune system.
Taking megadoses of a single vitamin does not. More is not necessarily better. Walk into a store, and you will find bottles of pills and herbal preparations that claim to "support immunity" or otherwise boost the health of your immune system.
Although some preparations have been found to alter some components of immune function, thus far there is no evidence that they actually bolster immunity to the point where you are better protected against infection and disease.
Demonstrating whether an herb — or any substance, for that matter — can enhance immunity is, as yet, a highly complicated matter.
Scientists don't know, for example, whether an herb that seems to raise the levels of antibodies in the blood is actually doing anything beneficial for overall immunity. Modern medicine has come to appreciate the closely linked relationship of mind and body.
A wide variety of maladies, including stomach upset, hives, and even heart disease, are linked to the effects of emotional stress. Despite the challenges, scientists are actively studying the relationship between stress and immune function. For one thing, stress is difficult to define. What may appear to be a stressful situation for one person is not for another.
When people are exposed to situations they regard as stressful, it is difficult for them to measure how much stress they feel, and difficult for the scientist to know if a person's subjective impression of the amount of stress is accurate.
The scientist can only measure things that may reflect stress, such as the number of times the heart beats each minute, but such measures also may reflect other factors. Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor; rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one's work.
Some scientists are investigating whether ongoing stress takes a toll on the immune system. But it is hard to perform what scientists call "controlled experiments" in human beings. In a controlled experiment, the scientist can change one and only one factor, such as the amount of a particular chemical, and then measure the effect of that change on some other measurable phenomenon, such as the amount of antibodies produced by a particular type of immune system cell when it is exposed to the chemical.
In a living animal, and especially in a human being, that kind of control is just not possible, since there are so many other things happening to the animal or person at the time that measurements are being taken. Despite these inevitable difficulties in measuring the relationship of stress to immunity, scientists are making progress.
Almost every mother has said it: "Wear a jacket or you'll catch a cold! Probably not, exposure to moderate cold temperatures doesn't increase your susceptibility to infection. There are two reasons why winter is "cold and flu season.
Also the influenza virus stays airborne longer when air is cold and less humid. But researchers remain interested in this question in different populations.
Some experiments with mice suggest that cold exposure might reduce the ability to cope with infection. But what about humans? Scientists have performed experiments in which volunteers were briefly dunked in cold water or spent short periods of time naked in subfreezing temperatures. They've studied people who lived in Antarctica and those on expeditions in the Canadian Rockies.
The results have been mixed. For example, researchers documented an increase in upper respiratory infections in competitive cross-country skiers who exercise vigorously in the cold, but whether these infections are due to the cold or other factors — such as the intense exercise or the dryness of the air — is not known.
A group of Canadian researchers that has reviewed hundreds of medical studies on the subject and conducted some of its own research concludes that there's no need to worry about moderate cold exposure — it has no detrimental effect on the human immune system.
Should you bundle up when it's cold outside? The answer is "yes" if you're uncomfortable, or if you're going to be outdoors for an extended period where such problems as frostbite and hypothermia are a risk. But don't worry about immunity.
Regular exercise is one of the pillars of healthy living. It improves cardiovascular health, lowers blood pressure, helps control body weight, and protects against a variety of diseases. But does it help to boost your immune system naturally and keep it healthy?
Just like a healthy diet, exercise can contribute to general good health and therefore to a healthy immune system.
