Immune System The immune system is a network of cells, tissues, and organs that work together to protect the body from infection. Although scientists have learned much about the immune system, they continue to study how the body targets invading microbes, infected cells, and tumors while ignoring healthy tissues.mmune System The immune system is a network of cells, tissues, and organs that work together to protect the body from infection.

A truffle is the fruiting body of an underground mushroom. Its spores are dispersed by fungivores, animals that eat fungi.Almost all truffles are found in close association with trees. There are hundreds of species of truffles that are big, but the fruiting body of some (mostly in the genus 'Tuber') are highly prized as a food.The 18th-century French gastronome Brillat-Savarin called these truffles the diamond of the kitchen.here are hundreds of species of truffles that are big, but the fruiting body of some (mostly in the genus 'Tuber') are highly prized as a food.

Truffles are the fruiting bodies of ectomycorrhizal fungi which live on and around the roots of certain types of trees. Unlike other types of mushrooms which grow above ground and produce wind-dispersed spores, truffles fruit below ground, having evolved to produce strong chemical aromas when mature.o. Although there are many species of truffle only a small number are sought after for culinary use and have commercial value. These are Tuber magnatum Pico (Italian White), Tuber melanosporum Vitt. (Perigord black), Tuber borchii Vitt.(Bianchetto) and Tuber aestivum Vitt. (Burgundy or summer truffle).
