pro·tein

 (prō′tēn′, -tē-ĭn)
n.
Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

[French protéine, from Late Greek prōteios, of the first quality, from Greek prōtos, first; see per in Indo-European roots.]

pro′tein·a′ceous (prōt′n-ā′shəs, prō′tē-nā′-), pro·tein′ic (prō-tē′nĭk), pro·tein′ous (prō-tē′nəs) adj.

protein

(ˈprəʊtiːn)
n
(Biochemistry) any of a large group of nitrogenous compounds of high molecular weight that are essential constituents of all living organisms. They consist of one or more chains of amino acids linked by peptide bonds and are folded into a specific three-dimensional shape maintained by further chemical bonding
[C19: via German from Greek prōteios primary, from protos first + -in]
ˌproteinˈaceous, proˈteinic, proˈteinous adj

pro•tein

(ˈproʊ tin, -ti ɪn)

n.
1. any of numerous organic molecules constituting a large portion of the mass of every life form, composed of 20 or more amino acids linked in one or more long chains, the final shape and other properties of each protein being determined by the side chains of the amino acids and their chemical attachments.
2. plant or animal tissue rich in such molecules, considered as a food source.
[< French protéine (1838) < Greek prōte(îos) primary + French -ine -in1]
pro`tein•a′ceous (-tiˈneɪ ʃəs, -ti ɪˈneɪ-) adj.

pro·tein

(prō′tēn′)
One of a large class of complex organic chemical compounds that are essential for life. Proteins play a central role in biological processes and form the basis of living tissues. They consist of long, looping or folding chains of smaller compounds called amino acids. Enzymes, antibodies, and hemoglobin are examples of proteins.

protein

  • albumen, albumin - Albumen is the white of an egg, from Latin albus, "white"; albumin is a protein within the albumen.
  • protein - Pronounced PRO-teen or PRO-tee-un, it comes from Greek proteios, "primary," as these compounds are essential to all living organisms.

The HIV reservoir consists of infected cells that contain DNA molecules that encode HIV proteins. These cells are in a resting state in which they do not produce any part of the virus.
HIV proteins are detected in EVs of HIV+ patients and HIV Nef is the most prevalent protein found [18-21].

This is then followed by a course of the drug Vorinostat that awakens the dormant T-cells, which then begin producing HIV proteins that act as a homing beacon to the immune system.
"Manufacturing of engineered HIV proteins in consistent quantity and quality is critical for further development of promising vaccine candidates toward early clinical testing," said Labeeb Abboud, senior vice president, business development at IAVI.
* Second-generation tests relied on recombinant HIV proteins or synthetic peptides to detect HIV-1/2 IgG antibodies.
The reactivation research strategy is to pharmacologically reactivate the HIV expression within those latent cells, thereby expressing the HIV proteins and making the cell a target for pharmacologic or immune elimination.
Several HIV proteins especially Vpr, Tat, and Nef exhibit molecular mimicry with respect to TNF signaling in HIV-infected cells particularly in macrophages (Figure 2).
So the team engineered an HIV envelope protein that lacks specific glycan and ran binding tests, in which the germline antibodies were able to bind the modified HIV proteins. They also verified that the modified HIV protein was capable of starting the process of antibody maturation in B cells, jumpstarting an immune response that could result in broadly neutralizing antibodies.
In previous studies, researchers and scientists usually combine various whole HIV proteins to create vaccine, and sadly, none actually worked and failed to reach commercial vaccine status.
The engineered stem cells developed into a large population of mature, multi-functional HIV-specific CDS cells that could specifically target cells containing HIV proteins. The researchers also discovered that HIV-specific T cell receptors have to be matched to an individual in much the same way an organ is matched to a transplant patient.
