The complement system is one of the most important secreted mediators of innate immunity. It comprises a group of heat labile soluble serum proteins, which are usually inactive unless activated by a trigger such as detection of antigen–antibody complexes or microorganisms. The system produces a rap...
“I study, in particular, the part of immunity that is not specific, meaning that it works against every type of infection. It is called innate immunity. We also call it inflammation, which is a very efficient protective immune mechanism,” Boraschi explained her research field in a simple ...
An example of a cell entering the sinus via a slit is illustrated (yellow arrow). Red pulp macrophages (pink) are located in the cord and some closely associate with the sinus wall. Aged or damaged red blood cells that become too stiff to squeeze between the slits are quickly phagocytose...

Answer to: (a) Which defense prevents microbial invasion into the body, innate or adaptive immunity? (b) Explain why. (c) Give an example. By...
Association analysis using the Genotype-Tissue Expression (GTEx) dataset42,43 showed that, compared to noncarriers, rs1921622 A allele carriers exhibited a lower transcript level of sST2, but not ST2L, in certain brain regions (for example, hippocampus and frontal cortex; P < 0.05; Fig....
. Cells with impossible marker combinations (for example, both CD3+ and CD19+) were excluded, and only those with an I-index > 0 were retained, yielding 188 immunophenotypes. The 188 immune cell subsets selected for inclusion in the correlative analyses were then divided into two groups...
For example, songbirds have the innate ability to produce the typical songs of their species, but most of them must be taught how to do it by older birds.Figure 2: Chimpanzees and other great apes use gesture-call communication systems. Great apes and other primates have relatively complex ...
increase survival of matureosteoclasts. While osteoblasts andosteocytesare derived from cells in the mesenchymal lineage, they are also regulated by innate immune stimuli and also by other immune cells. An example is that activation of the pattern recognition receptors TLRs on osteoblasts orstromal ...
HMGB-1 is also a prime example of a class of molecules known as “alarmins” or danger/damage-associated molecular patterns (DAMPs).47Broadly speaking, DAMPs represent a class of molecules that normally exist in the intracellular compartment at baseline, but are released from damaged cells into...
