When a pathogen “attacks” us, our immune machine kicks in and protects us from illness by way of “killing” that destructive invader. Even though in a fully other approach, crops even have their very own immune machine, which protects them from quite a lot of infections.
When a pathogen enters the human frame, there are two varieties of cells that come into play: macrophages and dendritic (or Langerhans) cells. The best way those protection cells paintings is to at once engulf the intruder, digest and kill it, or to engulf cells which have been attacked by way of the pathogen, getting rid of them in the similar approach. Each macrophages and dendritic cells act towards any invaders that input the frame – with out first figuring out “who” is attacking – in the course of the so-called innate immune reaction.
When a pathogen is digested, those protection cells take small molecules from it (referred to as antigens) and position them at the out of doors. After that, they manner different protection cells, referred to as T lymphocytes, and “teach” them those antigens. On this approach, T lymphocytes learn how to acknowledge the pathogen and, when it assaults once more, they are going to wreck it extra temporarily and successfully.
