Experiments Shed Light on How Forces Affect T-Cell FunctionsT-cells are the body’s sentinels, patrolling every corner of the body in search of foreign threats such as bacteria and viruses. Receptor molecules on the T-cells identify invaders by recognizing their specific antigens, helping the T-cells discriminate attackers from the body’s own cells. When they recognize a threat, the T-cells signal other parts of the immune system to confront the invader.These T-cells use a complex process to recognize the foreign pathogens and diseased cells. In a paper published this week in the journal Cell, researchers add a new level of understanding to that process by describing how the T-cell receptors (TCR) use mechanical contact – the forces involved in their binding to the antigens – to make decisions about whether or not the cells they encounter are threats.Read more: http://www.laboratoryequipment.com/news/2014/04/experiments-shed-light-how-forces-affect-t-cell-functions

Fruits, Veg Hold Benefits Even in Small AmountsConversationThe findings of a study from researchers at UCL suggested we should be eating seven different portions of vegetables and fruit a day, rather than the five as currently recommended. But it’s clear that many people already find it hard to meet the target of five, let alone seven, and suddenly it feels the goal posts have moved. And if there’s no chance of getting anywhere near seven, then you might as well just not listen.Not many people achieve the recommendation of five portions per day – the current average intake is just under four. Seven-a-day made good national headlines, but if you really dissect the research findings what you discover is that the reduced risk of dying from cancer and heart disease is associated with any increased intake of vegetables and fruit over and above one portion per day. So the more you eat, the more you reduce your risk. This means that if you eat three or four portions a day, you’re still doing well.Read more: http://www.laboratoryequipment.com/news/2014/04/fruits-veg-hold-benefits-even-small-amounts
