Equal protection

As well as animals, plants also have their own immune system is also complex as nostro.Non fact that everyone knows the famous "aspirin", whose active ingredient is acetyl salicico, comes from a compound that plants exploit for their defense for thousands of years as salicylic acid or other components such as, for example, ROS, reactive oxygen compounds. were born But when these defensive systems? Pamela Ronald, University of California botany and Brucer Beutler, geneticist Script Research Institute, published a study in Science which state that the innate immune system of plants and animals works the same modo.Ma take a step back, what is the innate immune system? and what differs from that acquired? The innate immune system mediates the first protection against infections, usually consists of epithelial barriers, through specialized cells and substances near naturally equipped with antibiotic power, also potentiates the work immunity acquisita.L 'immunity acquired instead, provides a slower response but more specific, is mediated by antibodies (produced by B lymphocytes) and by T lymphocytes

 The researchers, with a study that lasted 15 years, they found an amazing similarity in the way in which these two kingdoms difendono.I researchers examined the nature of the protein receptors that recognize and attach to antigens encouraging response immunitaria.Nonostante the species-specificity of the proteins have found rich regions of leucine, amino acid important for binding antigenico.Inoltre, once recognized the intruder, in a similar manner both plants and animals, lal trigger immune response with the same proteins, those of the non-complex kinase RD.Ecco another proof of the fact that all living beings are derived from a common ancestor, even if one were needed.
