Nuestro sistema inmunitario

Every day of our lives, our immune system remains alert, defending us from a multitude of agents with the potential to cause us disease: parasites, bacteria, viruses, cancer cells, etc. The work is constant. This permanent fight between our defense cells and multiple pathogenic agents usually goes unnoticed by us until a failure in the defensive system reminds us that we are vulnerable and that our immune system is imperfect. After millions of years of evolution, the human immune system has been equipped with molecules, cells, tissues and organs capable of orchestrating extremely complex and directed responses against the most diverse threats. As it does? What elements act and where are they? In what way can it fail? Why do autoimmune diseases, allergies and even cancer occur? And immunodeficiencies? How do sex, age, pregnancy or the microbiome affect them? This book aims to delve into the world of immunology by reviewing essential concepts and taking a brief historical tour to learn what it is, how it works and how we can contribute to our own immunity.
