The department of Cell Biology and Immunology (CBI) gathers 20 groups interested in studying molecular mechanisms of mammalian cell organization and function. The research groups that compose the CBI share common experimental approximations, technologies and an interest in a limited set of cell processes: differentiation, motility, polarity, cell-cell interaction and signal transduction. The CBI’s research activities are structured around two major areas of research interest: the immune system and cell processes. The groups interested in the immune system tackle various fundamental aspects including how immune cells differentiate from hematopoietic precursors, how immune cells interact with parasites and viruses and the processes of antigen presentation and antigen recognition. The encounter with the antigen and the resulting activation of intracellular signaling pathways is also studied and compared with other cell systems. The groups studying cell processes focus on dissecting the molecular mechanisms that govern cell polarization, intracellular trafficking of proteins, cell adhesion and cell migration. These processes are studied in immune cells, epithelial cells and the endothelium. An important part of the CBI is dedicated to the T cell as a model system: T cell development and its perturbation during malignant transformation, mechanisms of antigen presentation by MHC molecules linked to arthropathies, antigen presentation of viral proteins and mechanisms of cyotoxic T cell killing, mechanisms of T cell adhesion and its regulation by tetraspanins, and T cell receptor signaling mechanisms influencing differentiation to pro-inflammatory effector T cells. Viruses and intracellular protozoa affecting inflammation and causing cardiac damage are also being investigated as models of perturbation of the immune system. Interestingly, inflammation and the cardiovascular system are also approached from the side of endothelial cells and signaling mechanisms, with repercussions on diabetes and obesity. Finally, the cytoskeleton, the polarization of epithelial cells, intracellular vesicular transport, and the loss of epithelial features during epithelial-to-mesenchimal transition and its impact on fibrosis and cancer metastasis are being actively investigated. The research carried out in the CBI has a clear translational angle, applying to cancer, inflammation and autoimmune diseases.

What are cookies?

A cookie is a file that is downloaded to your computer when you access certain web pages. Cookies allow a web page, among other things, to store and retrieve information about the browsing habits of a user or their equipment and, depending on the information they contain and the way they use their equipment, they can be used to recognize the user.

Types of cookies

Classification of cookies is made according to a series of categories. However, it is necessary to take into account that the same cookie can be included in more than one category.

  1. Cookies according to the entity that manages them

    Depending on the entity that manages the computer or domain from which the cookies are sent and treat the data obtained, we can distinguish:

    • Own cookies: those that are sent to the user's terminal equipment from a computer or domain managed by the editor itself and from which the service requested by the user is provided.
    • Third party cookies: those that are sent to the user's terminal equipment from a computer or domain that is not managed by the publisher, but by another entity that processes the data obtained through the cookies. When cookies are installed from a computer or domain managed by the publisher itself, but the information collected through them is managed by a third party, they cannot be considered as own cookies.

  2. Cookies according to the period of time they remain activated

    Depending on the length of time that they remain activated in the terminal equipment, we can distinguish:

    • Session cookies: type of cookies designed to collect and store data while the user accesses a web page. They are usually used to store information that only is kept to provide the service requested by the user on a single occasion (e.g. a list of products purchased).
    • Persistent cookies: type of cookies in which the data is still stored in the terminal and can be accessed and processed during a period defined by the person responsible for the cookie, which can range from a few minutes to several years.

  3. Cookies according to their purpose

    Depending on the purpose for which the data obtained through cookies are processed, we can distinguish between:

    • Technical cookies: those that allow the user to navigate through a web page, platform or application and the use of different options or services that exist in it, such as controlling traffic and data communication, identifying the session, access to restricted access parts, remember the elements that make up an order, perform the purchase process of an order, make a registration or participation in an event, use security elements during navigation, store content for the broadcast videos or sound or share content through social networks.
    • Personalization cookies: those that allow the user to access the service with some predefined general characteristics based on a series of criteria in the user's terminal, such as the language, the type of browser through which the user accesses the service, the regional configuration from where you access the service, etc.
    • Analytical cookies: those that allow the person responsible for them to monitor and analyse the behaviour of the users of the websites to which they are linked. The information collected through this type of cookies is used in the measurement of the activity of the websites, applications or platforms, and for the elaboration of navigation profiles of the users of said sites, applications and platforms, in order to introduce improvements in the analysis of the data of use made by the users of the service.
