The Cell: An Image Library™ is a freely accessible, easy-to-search, public repository of reviewed and annotated images, videos, and animations of cells from a variety of organisms, showcasing cell architecture, intracellular functionalities, and both normal and abnormal processes. The purpose of this database is to advance research, education, and training, with the ultimate goal of improving human health.
Chemokines are best known for their classic leukocyte chemotactic activity, which is critical for directing the immune response to sites of infection and injury. However, recent studies have suggested that at least some chemokines may also interfere with infectious agents directly. Antimicrobial chemokines tend to contain amphipathic alpha helical secondary structure, and broad-spectrum activity against both Gram-positive and Gram negative bacteria, as well as fungi. Conversely, several bacteria have been identified that possess mechanisms for specifically blocking the antimicrobial activities of chemokines. Although the precise mechanisms by which chemokines and microbes disarm one another in vitro remain unknown, there is now emerging evidence in vivo that such interactions may be biologically significant. More research will be needed to determine whether chemokines with direct antimicrobial activity may be translated into a novel class of antibiotics.

KIR2DL4 is an unusual killer cell immunoglobulin-like receptor (KIR) family member in terms of its structure, expression, cellular localization, and signaling properties. The most conserved KIR in evolution, it is referred to as a framework KIR gene and is expressed by all natural killer (NK) cells and a subset of T cells. Although it has a long cytoplasmic tail that is typical of inhibitory KIR, engagement of this receptor results in the activation of NK cells, not for cytotoxicity, but for cytokine and chemokine secretion. Unlike all other KIRs, which are expressed on the surface of NK cells, KIR2DL4 resides in endosomes. It signals from this intracellular site for a proinflammatory and proangiogenic response, using a novel endosomal signaling pathway that involves the serine/threonine kinases DNA-PKcs and Akt. The only known ligand of KIR2DL4 is HLA-G. Soluble HLA-G accumulates in KIR2DL4+ endosomes. Unlike classical HLA molecules that serve as ligands for other KIR family members, in healthy individuals, HLA-G expression is restricted to the fetal trophoblast cells that invade the maternal decidua during early pregnancy. Since NK cells constitute the predominant lymphocyte subset at this site, the proinflammatory/proangiogenic outcome of the interaction between KIR2DL4 and soluble HLA-G supports a role for KIR2DL4 in the extensive remodeling of the maternal vasculature during the early weeks of pregnancy.

Host restriction factors are potent, widely expressed intracellular blocks to viral replication that are an important component of the innate immune response to viral infection. However, viruses have evolved mechanisms that antagonize restriction factors. Through evolutionary pressure for both host survival and virus replication, an evolutionary 'arms race' has developed that drives continuous rounds of selection for beneficial mutations in the genes encoding restriction factors and their viral antagonists. Because viruses can evolve faster than their hosts, the innate immune system of modern-day vertebrates is for the most part optimized to defend against ancient viruses, rather than newer viral threats. Thus, the evolutionary history of restriction factors might, in part, explain why humans are susceptible or resistant to the viruses present in the modern world.
Free Open Access Meducation (FOAM, #FOAMed) is essentially a personalized, continually expanding medical curriculum that embraces an individual's attention deficits, evolves as one learns, encourages active learning, and pushes the bounds of one 'ought' to know. Here's a good summary of FOAM. Life in the Fast Lane has an extensive list of FOAM resources and there's a new FOAM search engine.
Fluorescence illumination and observation is the most rapidly expanding microscopy technique employed today, both in the medical and biological sciences, a fact which has spurred the development of more sophisticated microscopes and numerous fluorescence accessories. Epi-fluorescence, or incident light fluorescence, has now become the method of choice in many applications and comprises a large part of this tutorial. We have divided the fluorescence section of the primer into several categories to make it easier to organize and download. Please follow the links below to navigate to points of interest.

Pearltrees is a place to collect, organize and share everything you like on the web. Aquí estoy coleccionando imágenes, videos, enlaces, revisiones, etc... para montar lecciones de Inmunología, Inmunopatología e Inmunoterapia a nivel Universitario.
Course Description Students in this course include clinical fellows, trainees in the pharmaceutical industry and practicing academic physicians who wish to enhance their understanding of immunology. Invited speakers lecture on the major topics in cellular and molecular immunology, including innate immunity, B cells, T cells and cytokines. Special sessions cover new advances in interventional clinical immunology and the molecular and genetic basis of immune-mediated diseases. There is ample opportunity for students to interact with the faculty outside the lecture room. Students are provided a syllabus and access to online lecture materials.
This series from UCSF's Osher Mini Medical School for the Public provides up-to-date information about how a normal immune system functions, and how doctors treat disorders of immunity.
Bellanti’s IMMUNOLOGY IV is a new, contemporary approach to teaching immunology that uses the most advanced pedagogical and online aids. Consisting of a full-color, heavily illustrated textbook plus an online service with animations, illustrations, interactive study questions and critical thinking aids, this is the perfect solution not only for faculty seeking to fully present this complex scientific discipline to students as well for members of the medical professions while focusing on its relation to real world clinical problem-solving. It is also the ideal reference for residents and practitioners preparing for certification and board examinations. The structure, content and pedagogy allow users to retain more knowledge in less time than with traditional methods.
