where they are activated by antigen-specific stimulation of their receptor complexes by APCs and differentiate into effector phenotypes that may either directly kill virally infected cells, provide helper signals to B lymphocytes for their activation, or mediate immunity to a number of distinct, infect...
Assisted reproduction provides a wide spectrum of treatments and strategies addressing infertility.However,distinct groups of infertile patients with unexplained infertility,congenital disorders,and other complex cases pose a challenge in in vitro fertilization(IVF)practices.This special cohort of patients is ...
Given a network and a grouping of nodes, the modularity measures the degree to which nodes are preferentially connected within the groups (Fig. 1 c and “Methods”). Modularity is calculated as the excess number of edges compared to randomly connected nodes, divided by the total number of ...
Some R groups are hydrophobic and tend to project to, and be buried in, the inside of a protein structure. Four amino acid R groups contain either a positive or negative charge and thus project to the water environment to the exterior of proteins. Other R groups are polar in nature and ...
cells TFH cells emerged as a distinct type with particular migratory properties of as they express the chemokine receptor CXCR5 which allows them to migrate into B cell follicles and germinal centres7,8. In addition, TFH cells are generally regarded as LN-resident cells that stay in the LNs ...
Olfactory information reaches the brain via the olfactory nerve. Theolfactory organsare particularly well developed in gymnophionans, and, on each side, distinct dorsal and ventral olfactory nerves reach the bulbs (Fig. 1). The olfactory bulbs of amphibians evaginate from the rostral telencephalic ...
These proteins, known as nucleic acid–binding proteins (NABPs), are expressed at different times to enable cells to perform essential functions during development and to respond to a series of stresses (8). Despite the considerable advances in understanding the important role of NABPs in aging,...
