By Vinicius L. Ferreira, Helena H. Borba, Aline de F. Bonetti, Leticia P. Leonart and Roberto Pontarolo. This chapter aims to describe and review the main important cytokines types notably interferons , including their biological activities, functions and structures.

Cytokines are small proteins that are crucial in controlling the growth and activity of other immune system cells and blood cells. When released, they signal the immune system to do its job. Cytokines affect the growth of all blood cells and other cells that help the body's immune and inflammation responses. They also help to boost anti-cancer activity by sending signals that can help make abnormal cells die and normal cells live longer. One specific type of cytokine is called a chemokine.

The cytokines are a relatively diverse group of low molecular weight 8,—30, daltons proteins that act to transmit information among the cells involved in immunological responses. On one level, they can be thought of as the "hormones" of the immune system. However, as will be explained shortly, the cytokines can have many important roles including cell activation, effector function for example, killing of virus-infected cells , immune suppression, and induction of cell differentiation.

Cytokines have context-dependent roles that dictate their normal physiological function; however, dysregulation or chronic activation of cytokine pathways can alter tissue balance away from a return to homeostatic quiescence toward disease-associated immunopathology. Cytokines are the chemical mediators that regulate immune cell homeostasis and coordinate signal-dependent immune responses. Cytokine signaling circuits include multiple regulatory checkpoints, which often involve feedback inhibition; this process allows tissues to return to a relatively quiescent non-inflammatory state of immunotolerance.

The Role of Inflammatory and Anti-Inflammatory Cytokines in the Pathogenesis of Osteoarthritis

Cytokines are peptides and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine , paracrine and endocrine signaling as immunomodulating agents. Their definite distinction from hormones is still part of ongoing research.

Osteoarthritis OA is the most common chronic disease of human joints. The basis of pathologic changes involves all the tissues forming the joint; already, at an early stage, it has the nature of inflammation with varying degrees of severity. An analysis of the complex relationships indicates that the processes taking place inside the joint are not merely a set that seemingly only includes catabolic effects. Apart from them, anti-inflammatory anabolic processes also occur continually. These phenomena are driven by various mediators, of which the key role is attributed to the interactions within the cytokine network.

About this article

Сердце ее готово было выскочить из груди. Было видно, что Хейл ей не поверил. - Может быть, хочешь воды. Она не нашлась что ответить. И проклинала .

Неужели Стратмор каким-то образом проскользнул наверх. Разум говорил ему, что Стратмор должен быть не наверху, а внизу. Однако звук повторился, на этот раз громче. Явный звук шагов на верхней площадке. Хейл в ужасе тотчас понял свою ошибку.

На вид за шестьдесят, может быть, около семидесяти. Белоснежные волосы аккуратно зачесаны набок, в центре лба темно-красный рубец, тянущийся к правому глазу.

 - Я гожусь тебе в матери. Могла бы не напоминать, - подумал. Мидж подошла к его столу. - Я ухожу, но директору эти цифры нужны к его возвращению из Южной Америки. То есть к понедельнику, с самого утра.

 - Я полагаю, Хейл держит этот пароль, глубоко запрятав его в компьютере, а дома, возможно, хранит копию. Так или иначе, он попал в западню. - Тогда почему бы не вызвать службу безопасности, которая могла бы его задержать. - Пока рано, - сказал Стратмор.  - Если служба безопасности обнаружит затянувшуюся надолго работу ТРАНСТЕКСТА, перед нами возникнет целый ряд новых проблем.

Через пять минут автобус, подпрыгивая, несся по темной сельской дороге. Беккер повернулся к панку. - Этот тарантас когда-нибудь остановится. - Еще пять миль. - Куда мы едем.

Cytokines: Introduction

На что же уходит такая уйма времени. - спросил он, обращаясь в пустоту и чувствуя, как покрывается. Наверное, придется потревожить этой новостью Стратмора.

In order to mount and coordinate an effective immune response, a mechanism by which lymphocytes, inflammatory cells and haematopoietic cells can communicate with each other is required.
