Macrophages comprehend a heterogeneous mononuclear phagocytic population with wide range phenotypes and roles in homeostasis maintenance and diseases, such as infections, autoimmunity and cancer. Technology improvements enable researchers to track different macrophage populations in different tissues and situations and hypothesize on their role in promoting inflammation or stimulating tissue repair. Through innate immune recognition system macrophages can launch several effector artilleries that culminate in the production of various types of inflammatory mediators as cytokines, chemokines, lipid mediators and oxygen reactive species, which in turn, influence the behavior of other cells. Fur...
Through recent research, there has been a significant number of findings involving the biology of macrophages. Beyond the 1st line of defense, macrophages have several specific characteristics across different tissues, organs, and systems. Macrophages comprehend a heterogeneous phagocytic population with wide range phenotypes, and tissue-specific functions, such as bone resorption, extracellular matrix production, red blood cells and bacteria removal, among others. Through innate immune receptors macrophages can modulate several pathways that culminate in the production of various types of inflammatory mediators such as chemokines, cytokines, oxygen reactive species, and lipid mediators whic...

Skin is the largest organ of the body and is necessary for survival, since it performs many functions such as providing a physical barrier to the external environment, sensation, retention of normal hydration and thermal regulation. Significant skin loss is associated with high mortality and morbidity in the acute phase, and with physically and cosmetically drastic scarring in the long term. Although there are a number of tissue-engineered products in the clinic that are used as skin substitutes to promote healing of traumatic burn and diabetic wounds, yet they lack several important functions including those provided by the appendages such as the hair follicles, sebaceous and sweat glands. ...
Sesudah mikroskop dibuat untuk pertama kali pada akhir 1600-an, para ahli menggunakannya untuk meneliti makhluk hidup, dan mereka melihat bahwa seluruh kehidupan terbentuk dari satuan-satuan kecil yang utuh dan mampu mengatur diri sendiriÑsel. Penemuan sel mengubah bidang biologi dan kedokteran untuk seterusnya. Tubuh kita, organ kita, diri kitaÑjantung, darah, otakÑdibangun dari sel-sel. Pengetahuan bahwa tubuh manusia adalah ekosistem sel melahirkan kedokteran baru yang didasari manipulasi sel untuk menyembuhkan. Berbagai gejala dan penyakit dipahami sebagai gangguan fungsi sel atau sistem sel. Oleh karena itu dikembangkan pula berbagai penanganan dan terapi berbasis selÑtransfusi dara...
Aan het einde van de zeventiende eeuw doen de Engelse geleerde Robert Hooke en de Nederlander Antoni van Leeuwenhoek een ontdekking die de wetenschap voorgoed verandert. Door hun zelfgemaakte microscopen zien ze dat organismen complexe verzamelingen zijn van minuscule, opzichzelfstaande systemen. Ons hele wezen – ons lichaam, onze organen – is samengesteld uit deze eenheden. Hooke doopt ze ‘cellen’. Deze nieuwe kijk op het menselijk lichaam leidt de geboorte in van de moderne geneeskunde, waarbij aandoeningen worden beschouwd als het samenspel van zich afwijkend gedragende cellen en artsen proberen die te behandelen door cellen te manipuleren. Zo ontstaat een nieuwe mens. In Het lied van de cel neemt Siddhartha Mukherjee ons mee in de wereld van de cellen en verweeft hij de verhalen van wetenschappers, artsen en patiënten met zijn eigen ervaringen als arts en onderzoeker. Net als in zijn twee voorgaande boeken biedt hij de lezer een panoramische én intieme blik op wat het betekent om mens te zijn.
Tras los éxitos de El emperador de todos los males y El gen , Siddhartha Mukherjee se adentra en la increíble y apasionante historia de la célula. «En un relato a la vez lírico y amplio, Mukherjee nos lleva a través de una historia de la comprensión humana: desde el descubrimiento en el siglo XVII de que estamos formados por células hasta la actual tecnología de vanguardia para manipular y desplegar células con fines terapéuticos». The New Yorker Bienvenidos a la apasionante historia de la célula.
