Insulin can boost your immune system, here’s how

Insulin can boost your immune system, here’s how

Insulin, a peptide hormone produced by beta cells of the pancreatic islets, boosts immune health, according to a new study. Toronto General Hospital Research Institute (TGHRI) scientists have identified a specific insulin signalling pathway that, when activated, revs up the response of T cells in the immune system to divide rapidly and secrete cytokines, chemical messenger proteins that activate the rest of the immune system. A fast and effective immune response protects us against disease and life-threatening infections by destroying infected cells or microbes, while a wrong or inefficient one can…

Mums, take it easy. Maternal depression may affect child’s immune system

Mums, take it easy. Maternal depression may affect child’s immune system

Turns out, depression in mothers may have long-term effects on their children’s stress and physical well-being. In a new study, researchers followed 125 children from birth to 10 years. At 10 years, mother’s and children’s cortisol (CT) and secretory immunoglobulin (s-IgA)–markers of stress and the immune system–were measured, mother-child interaction was observed, mothers and children underwent psychiatric diagnoses, and children’s externalizing and internalizing symptoms were reported. Depressed mothers had higher CT and s-IgA levels and displayed more negative parenting, characterised by negative effect, intrusion, and criticism. Children of depressed mothers…

Gene That Strengthens Immune System Identified

Gene That Strengthens Immune System Identified

The gene that strengthens the human immunity system has been identified by Australian scientists, it was revealed on Monday. The Commonwealth Scientific and Industrial Research Organisation (CSIRO)identified the gene that plays a critical role in regulating the body’s immune response to infection including cancer and diabetes. The gene has existed for 500 million years. Its identification could lead to the development of new treatments for a “variety of diseases including cancer, diabetes and inflammatory disorders such as rheumatoid arthritis”, said CSIRO researcher Cameron Stewart. “Our immune system produces proteins called…

Moms-to-be, take care of your health. Your immune system may influence baby’s brain

Moms-to-be, take care of your health. Your immune system may influence baby’s brain

The state of a woman’s immune system during pregnancy may shape the connectivity of her child’s brain, suggests a study, emphasising the influence of maternal health on a child’s susceptibility to psychiatric disorders later in life. The findings showed that short and long-term brain functioning can be influenced by immune system activity during the third trimester of gestation. Infections, stress, illness, or allergies are commonly known to trigger immune responses. When the body’s immune system detects one of these factors, two proteins namely IL-6 and CRP are released as part…

Do you often take antibiotics? Beware, it may affect your immune system

Do you often take antibiotics? Beware, it may affect your immune system

Researchers at the University of Virginia’s school of medicine in Charlottesville, US have found that antibiotic use made neutrophils less effective in fighting infections and weakened the intestinal barrier against invading bugs. Researcher Koji Watanabe said that neutrophils play an important role as a first-line ‘innate immune response’ when foreign pathogens invade. “We found that antibiotic disruption of the natural microbes in the gut prevented this from happening properly, leaving the gut susceptible to severe infection,” Watanabe added. The team used lab mice to determine how the decrease in natural intestinal flora…

Brain-based immune proteins may regulate sleep

Brain-based immune proteins may regulate sleep

Sleep may be regulated in parts by several brain-based immune proteins, says a study that could pave the way for new therapies to treat chronic sleepdisorders and sleep disturbances secondary to other diseases. The immune proteins — collectively called inflammasome NLRP3 — recruit a sleep-inducing molecule to trigger somnolence following sleep deprivation and exposure to a bacterial toxin, showed results of the study published in the journal Brain, Behavior, and Immunity. Animals lacking genes for this protective immune complex showed profound sleep aberrations. “Our research points, for the first time,…

No Time to Sleep? You Could Be Hampering Your Immune System

No Time to Sleep? You Could Be Hampering Your Immune System

Why do we need to rest? There’s always so much to do and we have such little time. We have deadlines to meet and goals to achieve that we often convince ourselves that four to five hours of sleep time is more than enough. Now just ask yourself one question – do you want to be at the best of your health and live long? Living a healthy and balanced life takes dedication and effort, and you shouldn’t take it for granted. What we often fail to understand is that…

Doctors arm immune system to fight cervical cancer cells

Doctors arm immune system to fight cervical cancer cells

Doctors were bewildered when they went through the case sheet of a woman who was diagnosed with advanced cervical cancer nearly 10 years ago. More than a year after a full dose of radiotherapy, cancerhad spread to the lung. By then the disease should have claimed her life. Yet, she continues to visit them for periodic checks. Tests show she is free of the ailment. When diagnosed with cancer, her oncologist at the Cancer Institute (WIA) here had included her name for an experimental treatment – immunotherapy. Rather than directly…

Immune molecule deficiency increases risk of Epstein-Barr

Immune molecule deficiency increases risk of Epstein-Barr

‘ WASHINGTON, Dec. 23 (UPI) — Researchers from the National Institutes of Health National Institute of Allergy and Infectious Diseases, or NIAID, have found a genetic immune disorder causing increased risk and poor control of Epstein-Barr virus and EBV-associated cancer. The team studied two unrelated sets of siblings with uncontrolled EBV, which developed into Hodgkin’s lymphoma in three of the children. Researchers found the cause of their disease was a lack of the CD70 protein, which is found on the surface of different types of immune cells. The children also…

Bask in the sunlight to energise your immune cells

Bask in the sunlight to energise your immune cells

Bask in the sunlight to energise your immune cells Apart from helping for a healthier living by producing vitamin D, getting some sunlight may also energise T cells — immune cells — that play a central role in fighting infections in the human body, a study has found. “We all know sunlight provides vitamin D, which is suggested to have an impact on immunity, among other things. But what we found is a completely separate role of sunlight on immunity,” said Gerard Ahern, Associate Professor at the Georgetown University in…
