Immune system cellsuse several different types of receptors (a membrane-bound or intracellular receptor) to recognize antigens, and then translate the receipt signal into a meaningful cellular response such as cell division or differentiation (Roddie, O'Reilly, Dias Alves Pinto, Vispute, & Lowdell...

Ageing of the immune system, or immunosenescence, contributes to the morbidity and mortality of the elderly1,2. To define the contribution of immune system ageing to organism ageing, here we selectively deleted Ercc1, which encodes a crucial DNA repair protein3,4, in mouse haematopoietic cells ...

It has a pivotal role in human health by contributing to various physiological processes and influencing immune system function. Microbiomes in a variety of body organs and its association with human health have been discussed. Moreover, the importance of the digestive (oral cavity, stomach, and ...
These clusters were further annotated as brain, immune, muscle, metabolism, mucoid, nerve conduction and adipose&&gland, respectively. The development origins of organs were also labeled outside the map circle in red, blue and green, corresponding to endoderm, mesoderm and ectoderm respectively. The...
Until now, though, two technical problems have stood in the way of (妨碍)routinely transplanting animal organs into people. One is that the recipient’s immune system (免疫系统)must be persuaded to tolerate a big chunk of (一大块)foreign tissue(人或动植物身体的组织). The other is that swa...
of cells – not number of cells Smooth Muscle ¾ Smooth muscle is involuntary and not striated ¾ Found in blood vessels and internal organs, like in the digestive system ¾ Contracts slowly but can remain contracted for a long time 5 Nervous Tissue ¾ Found in brain, spinal cord, ...
In the inner ear, cochlear and vestibular sensory epithelia utilize grossly similar cell types to transduce different stimuli: sound and acceleration. Each individual sensory epithelium is composed of highly heterogeneous populations of cells based on ph
Lead is well known environmental pollutant, which can cause toxic effects in multiple organ systems. However, the influence of lead oxide nanoparticles, frequently emitted to the environment by high temperature technological processes, is still concealed
