Hormones have a wide range of effects and modulate many different body processes. The key regulatory processes that will be examined here are those affecting the excretory system, the reproductive system, metabolism, blood calcium concentrations, growth, and the stress response. Hormonal Regulation of...
whereas the movement of other solutes is passive, which does not require energy. Active transport allows cells to move a specific substance against its concentration gradient through a membrane protein, requiring energy in the form of ATP. For example, the sodium-potassium...
Magnesium is a required ingredient of the energy-production process that occurs inside the tiny structures within cells. The molecule ATP, or adenosine tri-phosphate, is the fundamental unit of energy used in human cells. Many of the functions carried out by cells require ATP to provide the ene...
Our objective is to focus this review on the ribosome biogenesis processes occurring in the nucleoli that might help to decipher the global organization of nuclear functions. We describe nucleolar organization and dynamics, propose our view on nucleolar targeting, report the relationship between the nuc...

A neuron consists of a nerve cell body and its processes. There are several dendrites associated with the cell body and 1 long extension: an axon that travels to an end organ with branches terminating in peripheral synaptic terminals. Nerve fibers can be either myelinated or unmyelinated (see...
Certainly, additional studies are warranted to confirm the role of APOE and interacting proteins in neurodegenerative processes. Recent investigations demonstrate that the bridging integrator 1 protein (BIN1) is linked to endosomal trafficking leading to tau pathology. Meta-analysis shows positive ...
P2X7 receptor (P2X7R) serves as a unique ATP-gated cation channel [204]. Growing studies have suggested that the interaction between P2X7R and the nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) inflammasome associated with the development of AIDs, including MS, SL...
[51]. Additionally, CTLA-4 reduces T follicular regulatory (Tfr) and T follicular helper (Tfh) cell expansion, which is one way that CTLA-4 controls B cell responses [52]. By inhibiting effector and proliferative processes, CTLA-4 on Treg cells may control memory CD8+T cells’ inactivity ...
The choice of a run at ∼65% of the maximum aerobic power (Vo2max), i.e., at a mild intensity, allowed the untrained hamsters to respond during 2 h to the energy demands of the run, and favored the maintenance of aerobic oxidative processes to fuel the muscular efforts, thus ...
