The inverse relationship between the numberof infections early in life and atopy has been interpreted asthe "hygiene hypothesis." That is, many infections early inlife promote the development of T helper type 1 cytokines, whilefewer infections early in life favor the development of T helpertype 2 (Th2) cytokines and atopy. An alternate interpretationof the same data, that atopy is protective against infectionsearly in life, is rarely considered. With epidemiologic, historical,and immunologic data, I suggest that human evolution has favoredindividuals with an atopic predisposition. Th2 immune responsespromote parity, and ensure successful pregnancy and term birth;provide the infant protection against infections and the inflammationinduced by common pathogens in the first years of life untilthe immune system matures; and protect young adults exposedto viral respiratory pathogens. These traits are of particularvalue with the advent of industrialization, especially so inthe era prior to the development of antibiotics. This theorycontradicts the assumption that there is no biological or evolutionaryadvantage for allergic disease to exist in humans and has significantimplications for our current and future treatments of allergicdiseases.</span></div><p> </p><p style="font-style: italic; color: rgb(0, 102, 0);"><strong>Key Words:</strong> allergic rhinoconjunctivitis • asthma • atopy • eosinophils • evolution • IgE • influenza • nitric oxide • T helper type 1/T helper type 2 • viral infection</p><br /><span style="color: rgb(0, 0, 0);"><br />Un saludo,<br /><br />Javier</span><span style="font-style: italic; color: rgb(153, 51, 0);"><br /></span></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/34967052-115976995724800711?l=med-darwiniana.blogspot.com' alt='' /></div>Javier Villafuerte-Gálvezhttp://www.blogger.com/profile/11112044753071104928noreply@blogger.com1tag:blogger.com,1999:blog-34967052.post-1159371428797120052006-09-27T10:33:00.000-05:002006-09-27T10:43:50.716-05:00<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/4806/3731/1600/boton_blogsperu10.gif"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="http://photos1.blogger.com/blogger/4806/3731/320/boton_blogsperu10.gif" alt="" border="0" /></a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/34967052-115937142879712005?l=med-darwiniana.blogspot.com' alt='' /></div>Javier Villafuerte-Gálvezhttp://www.blogger.com/profile/11112044753071104928noreply@blogger.com0tag:blogger.com,1999:blog-34967052.post-1159167051281689072006-09-25T01:42:00.000-05:002006-09-25T01:50:51.293-05:00Hola a Todos,<br /><br />Aquí va otro link a un artículo muy interesante hecho en nuestro propio continente. Da una revisión general al tema. Ojo: este está en español.<br /><br />Cita: Spotorno AE, Medicina evolucionaria: una ciencia básica emergente , Rev Méd Chile 2005; 133: 231-240 [ <a href="http://scielo-test.conicyt.cl/pdf/rmc/v133n2/art13.pdf">http://scielo-test.conicyt.cl/pdf/rmc/v133n2/art13.pdf</a> ]Accedido 25/09/2006 1h40am<br /><br /><strong>Resumen:</strong><br /><div align="justify"><br /><span style="font-size:85%;color:#993300;">Evolutionary Medicine is an emergent basic science that offers new and varied perspectives to the comprehension of human health. The application of classic evolutionary theories (descent with modification, and natural selection) to the human organism, to its pathogens, and their mutual co-evolution, provides new explanations about why we get sick, how we can prevent this, and how we can heal. Medicine has focused mainly on the proximate or immediate causes of diseases and the treatment of symptoms, and very little on its evolutionary or mediate causes. For instance, the present human genome and phenotypes are essentially paleolithic ones: they are not adapted to modern life style, thus favoring the socalled diseases of civilization (ie: ateroesclerosis, senescence, myopia, phobias, panic attacks, stress, reproductive cancers). With the evolutionary approach, post-modern medicine is detecting better the vulnerabilities, restrictions, biases, adaptations and maladaptations of human body, its actual diseases, and its preventions (Rev Méd Chile 2005; 133: 231-40).</span></div><br />Saludos, Javier<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/34967052-115916705128168907?l=med-darwiniana.blogspot.com' alt='' /></div>Javier Villafuerte-Gálvezhttp://www.blogger.com/profile/11112044753071104928noreply@blogger.com0tag:blogger.com,1999:blog-34967052.post-1159147814003360672006-09-24T20:21:00.000-05:002006-09-24T20:30:14.010-05:00Hola a todos,<br /><br />La primera vez que oí de medicina darwiniana fue durante el curso de biología I en la UPCH. Desde ese momento he tenido fuerte interés en este tema, sin embargo, no he leído sobre este en la medida que quisiera. El fin de este blog es reunir a gente interesada en el tema, estudiantes, profesores, o cualquiera, para poder intercambiar recursos (artículos, libros, webs), opiniones personales o institucionales. Algo así como un simposio virtual.<br /><br />Empiezo por mandar este link:<br /><br />Harris et al, Evolutionary explanations in medical and health profession courses: are you answering your students' "why" questions?, <strong>BMC Medical Education 2005</strong>, 5:16 doi:10.1186/1472-6920-5-16<br /><a href="http://www.biomedcentral.com/1472-6920/5/16">http://www.biomedcentral.com/1472-6920/5/16</a><br /><br />Un saludo,<br /><br />Javier<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/34967052-115914781400336067?l=med-darwiniana.blogspot.com' alt='' /></div>Javier Villafuerte-Gálvezhttp://www.blogger.com/profile/11112044753071104928noreply@blogger.com0
