The hallmark of immune deficiency syndromes is frequent, severe or unusual infection. The pattern of infections can give an indication of the type of deficiency, although in young children, this may be difficult to judge. It is estimated that children have eight minor infections per year and it...
Fibroblasts are cells of mesenchymal origin and are the main producers of ECM in homeostatic conditions and in response to injury5. These cells are found in virtually every tissue, but their molecular signature is not preserved between organs6. Fibroblasts are activated in the inflammatory stage of...
4 Many studies7, 8, 9 have demonstrated that numerous blood-borne tumor cells transit the pulmonary capillary bed and enter the systemic circulation,10 which distributes them to all organs. Therefore, disseminating cells from the same primary tumor fail to grow in most organs although they do ...

mouse DCs promoted enhanced production of IFN-γ and IL-17, as quantified by ELISA (Fig.1e). These data demonstrate an age-specific activation of DCs that promotes Th1 and Th17 responses, two prominent CD4+T cell pro-inflammatory subsets that are involved in IRI and transplant rejection31,...

In response to tissue injury, the body initiates a chemical signaling cascade that stimulates responses aimed at healing affected tissues. These signals activate leukocyte chemotaxis from the general circulation to sites of damage. These activated leukocytes produce cytokines that induce inflammatory ...
1, it is the human body blood bank, when the body rest, quiet, it stores blood, when in motion, blood loss, hypoxia and other stress state, it also sends blood to the blood circulation, in order to increase blood volume. 2, the spleen is like a filter, when the blood in the ...
