transcriptome and chromatin landscape of inkt cells are shaped by subset differentiation and antigen exposure. t/f

Answers

Answer 1

“Transcriptome and chromatin landscape of iNKT cells are shaped by subset differentiation and antigen exposure.” This statement is: True.

What are iNKT cells and what shaped them?

iNKT stands for Invariant natural killer T, which are cells that can initiate or inhibit immune response just like the T lymphocyte. Although most of the iNKT subsets look similar, regardless of the tissue location, two things shape the transcriptome and chromatin landscape of iNKT. These cells are differentiated into three effector cell subsets, which are NKT1, NKT2, and NKT17. Whereas, researchers prove that antigen exposure leads to the remodel of iNKT cells by chromatin. Hence, the statement above is true.

there are several ways the immune system can defend the body against pathogens. click and drag to distinguish specific from nonspecific immunity.

Answers

The several ways how an immune system can defend the body against pathogens are:

1) Mechanical and chemical barriers as the first line of defense

2) The inflammatory response and phagocytosis are the second line of defense.

3) Natural killer cells and specific immunological responses serve as the third line of defense.

There are three layers of defense in immune function, which is the internal environment's defense against invading cells, proteins, and viruses. A series of barriers between the internal and external environments serves as the initial line of defense.

The innate inflammatory response (including phagocytosis) makes up the second line, while the adaptive immune responses and the innate defense provided by natural killer cells make up the third line.

Of course, the first two lines of defense do not apply to tumor cells that develop inside the body, thus the third line of defense must be used to combat them. This illustration is a condensed version of the complex immune system operation; in reality, there is a lot of mechanism overlap between various "lines of defense."

how many sets of chromosome 21 are present in each cell after 1) mitosis, 2) meiosis, and 3) if a nondisjunction event occurred during anaphase i?

Answers

Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move on to the third and final phase of meiosis: meiosis II.

At the end of meiosis I there are two haploid cells. Most of complete trisomy 21 is caused by chromosome nondisjunction that occurs during maternal meiotic division (∼90%). Errors occur more frequently in the first maternal meiotic division than in the second. Nondisjunction can occur during meiosis I and meiosis II, resulting in abnormal number of gamete chromosomes. The key difference between nondisjunction in meiosis 1 and 2 is that during meiosis 1, the homologous chromosomes do not separate while in meiosis II the sister chromatids do not separate. Each chromosome contains 1 DNA in anaphase II meiosis. The remaining centromeric cohesin is cleaved in anaphase II, allowing segregation of sister chromatids. The mother cell remains diploid in nature (46 chromosomes in each cell) after meiosis I. After meiosis II, when each mother cell divides into two gametes, each gamete cell contains 23 chromosomes.

For every adenine on one strand of DNA, there is a thymine on the opposing strand of DNA. For every cytosine on one strand of DNA, there is a guanine on the opposing strand of DNA. This is because DNA strands are complementary with each other.

The hereditary substance in humans and almost all other organisms is DNA, or deoxyribonucleic acid. Almost every cell in a person's body contains the same DNA. The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but a small amount can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are cell structures that convert food energy into a state that cells can use.

DNA stores information as a code composed of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA is made up of approximately 3 billion bases, with more than 99 percent of those bases being the same in all people.

why do lipoprotein particles (e.g. vldl) only have a monolayer of phospholipids instead of a typical lipid bilayer?

Answers

Lipoprotein particles only have a monolayer of phospholipids because the phosphate of the lipids interacts with the triglycerides and cholesterol esters of the particle. The monolayer protects the particles from bile acids.

What is the role of the phospholipid monolayer at the outer surface of lipoprotein particles?

The lipid monolayer, along with binding proteins, that surround lipid droplets is what helps stabilize the oil drop in the aqueous cell environment due to the amphipathic nature of these molecules.

What are the functions of lipid monolayer?

Lipid monolayers are used as experimental model systems to study the physical-chemical properties of biomembranes. With this purpose, surface pressure/area per molecule isotherms provide a way to obtain information on the packing and compressibility properties of the lipids.

What is the difference between monolayer and bilayer?

The difference is that in bilayers the flux of solution is expressed as a volume change of the vesicles and in monolayers as an area change. By extension, the same approach should apply to the surface pressure area lipid process.

Thus, the monolayer protects the particles from bile acids.

These unique cells interact mutualistically with corals. The coral gives zooxanthellae a safe environment and the substances necessary for photosynthesis. The coral receives oxygen production and waste removal assistance from the zooxanthellae in return.

What is Mutualistic relationship ?

When two organisms of different species "operate together," they are said to be in a mutualistic relationship since they both gain from it.Ticks and other skin-living parasites are eaten by oxpeckers when they settle on rhinos or zebras. The oxpeckers are fed, and the animals are protected from pests. Additionally, the oxpeckers fly upward and scream a warning when there is danger, which aids the symbiont (a name for the other partner in a relationship).

Mutualistic organisms developed alongside one another. Both was a component of the other's environment, thus while they each "made use of" themselves, it was to their mutual advantage.

A sort of mutually beneficial association between creatures of various species is referred to as mutualism. Two separate species interact with one another and, in certain situations, completely depend on one another for survival. This is a symbiotic interaction. Other symbiotic connections include commensalism and parasitism, in which one species gains while the other suffers (where one species benefits without harming or helping the other).

For a variety of crucial reasons, including the need for food, shelter, and protection as well as for reproductive functions, organisms live in mutualistic interactions.

Free tryptophan (TRP), which is a precursor to 5-HT, is transformed in the terminal axon of the serotonergic neuron . Tryptophan hydroxylase (TPH) and aromatic decarboxylase are the enzymes that catalyse the two steps of 5-HT production (DDC). The rate-limiting enzyme, TPH, comes in two different isoforms, TPH1 and TPH2. In neural tissue, the TPH2 isoform predominates [3, 4]. The vesicular monoamine transporter mediates the uptake of 5-HT into presynaptic storage neurotransmitter vesicles (SLC18A2). The transporter uses a proton gradient across the vesicular membrane to deposit serotonin into synaptic vesicles .

Physiological or behavioural adaptations to endure these periods have been required to ensure the survival of animals and plants that live in arid as well as periodically arid environments, such as transient streams or ponds. In particular, insects use a variety of defence mechanisms to prevent desiccation because they occupy a broad range of ecologically diverse niches. Typically, the change in mass under dry conditions is used to gauge an insect's desiccation resistance. As respiratory water loss is typically regarded as negligible, the overall mass difference among measurements before and following exposure to aridity is credited to body water loss.

The pressure in the lungs increases is not a part of inspiration.

The process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, primarily to flush out carbon dioxide and bring in oxygen, is known as breathing (or ventilation).

The process of taking air into the lungs is known as inspiration (inhalation). Because it is the result of muscle contraction, it is the active phase of ventilation. The diaphragm contracts and the thoracic cavity expands during inspiration. This lowers the intraalveolar pressure, allowing air to enter the lungs.

Expiration (exhalation) is the process by which air is expelled from the lungs during the breathing cycle. The relaxation of the diaphragm and elastic recoil of tissue during expiration reduces thoracic volume while increasing intraalveolar pressure. Expiration forces air from the lungs.
