What is TCR under Ethereum

1. Ethereum project draws lessons from the technology of bitcoin blockchain and expands its application scope. If bitcoin is a special calculator using blockchain technology, Ethereum is a general-purpose computer using blockchain technology. In short, Ethereum = blockchain + smart contract
compared with bitcoin, the biggest difference of Ethereum is that it can support a more powerful scripting language (technically speaking, Turing's complete scripting language), allowing developers to develop any application and implement any smart contract on it, which is also the most powerful point of Ethereum. As a platform, Ethereum can be compared with Apple's app store, on which any developer can develop applications and sell them to users. Each type of financial contract can be written as a smart contract in the form of program code<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

2. Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum"). The concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform". It began to develop through ICO crowdfunding in 2014
Ethereum is not only a database, it also allows you to run programs in the trusted environment of the blockchain. Ethereum has built a virtual machine named EVM (Ethereum virtual machine) on the blockchain. EVM allows code to be verified and executed on the blockchain, providing guarantee for code to run in the same way on everyone's machine. These codes are included in the smart contract. In addition to tracking the account balance, Ethereum uses the same method to save the EVM status on the blockchain. All nodes process the smart contract to verify the integrity of the contract itself and its output.

3. Ethereum, or eth for short, is a hot virtual investment currency recently. Known as the world's second largest market value of digital currency, second only to bitcoin

Ethernet coin is a kind of digital token of Ethereum, because Ethereum needs to use the token eth to support the application. Ethereum can also trade on trading platforms. In short, Ethereum is a platform and a programming language, which enables developers to build and release the next generation of distributed applications
Ethereum can be used to program, guarantee and trade, as well as to organize voting, domain name trading, financial trading platform, online crowdfunding, management company,
formulate contracts and most of the agreements, and integrate intelligent assets of hardware

the reason why the price of Ethereum can soar is not only e to the promotion and publicity of Ethereum community, but more importantly, virtual currency investors are looking for investment procts to replace bitcoin

a series of problems, such as bitcoin being regulated by the domestic central bank and being refused to apply for ETF listing, have led investors to look down on the prospect of bitcoin. At this time, the emergence and promotion of Ethereum are favored by these virtual currency investors

btctrade platform (bitcoin trading network) www.btctrade.com As the largest and most reliable trading platform in China, Ethereum trading was launched as early as November. Ethereum was about 50 yuan when it was online, and now it has risen to 300 yuan, which is amazing! It remains to be seen whether the future of eth will be as good as bitcoin!

4. Introction to TCR T cell antigen receptor (TCR)
TCR is a heterodimer α、β Each peptide chain can be divided into variable region (V region), constant region (C region), transmembrane region and cytoplasmic region; It is characterized by a short cytoplasmic region
TCR remarks
TCR belongs to immunoglobulin superfamily, and its antigen specificity exists in V region; Zone V (V) α、 V β There are three hypervariable regions CDR1, CDR2 and CDR3 respectively, and CDR3 has the largest variation, which directly determines the antigen binding specificity of TCR. When TCR recognizes MHC antigen peptide complex, CDR1 and CDR2 recognize and bind to the side wall of MHC antigen binding groove, while CDR3 directly binds to antigen peptide
TCR can be divided into two types: tcr1 and tcr2; Tcr1 is controlled by γ and δ Tcr2 consists of two chains α and β Two chains. In peripheral blood, 90% - 95% of T cells expressed tcr2; Moreover, any T cell expressed only one of tcr2 and tcr1.

5. In the past two years, what blockchain, bitcoin, Ethereum and token fire have been in a mess. The swindlers are the first! This cross-border credit rating project sounded so big last year. I thought I was going to enter the currency circle and have a good life. On impulse, I invested 50000 yuan in my down payment for buying a house! As a result, these swindlers have been selling coins for more than a year. They have cheated the big guys for so much money. The program of the big project has not changed. Now the official reply is that it will be online next month, that is to say, it will delay you for another may. Is there nothing in May? That completely shows that I fell into a pit. My down payment to you for the coffin is good! Although we cheated people blame us for being stupid, can the government manage and punish them?! I want to get something for nothing! At that time, the project will not be affected, and the money will certainly not come back. What can we do then? It's OK to send it to ya! They raise money illegally! Fraud!

6. TCR (teller cash recycler) is a kind of equipment used by bank tellers to handle cash business. It is composed of cash access cycle mole and cash box, and has the function of access and storage of cash. Like the bankbook printer, card reader and password keyboard, TCR is a kind of peripheral device. It does not have the automatic control ability of ATM, but needs to send instructions to control its various actions through additional application software.

TCR is a characteristic marker on the surface of all T cells. It binds with CD3 by non covalent bond to form tcr-cd3 complex. The function of TCR is to recognize antigen

BCR is an immunoglobulin on the surface of B cell membrane. It is not proced by antigen stimulation, but appears on the B cell membrane ring the development of B cells. It has the function of signal transction and presenting antigen to helper T cells

extended data:

1. Immunoassay

for cellular immunotherapy, the monitoring and evaluation of its efficacy is not simply determined by the immune activity of T cells or the strength of immune response, but is related to complex molecular immunological factors

The National Institutes of Health (NIH) cancer research center proposed a new viewpoint: clonal T cell receptor is the main factor causing tumor rection or disappearance in patients

in 2007, the University of London published a review article: "monoclonal T cell receptor gene -- a new cancer therapeutic agent". This article focuses on the role of clonal T cell receptor in immunity

In June 2008, the Seattle cancer research center published an article on "tumor autoimmune cell therapy" in the New England Journal of Medicine (nemj), which pointed out that T cells were taken from a 52 year old patient with melanoma, cloned in vitro, stimulated by antigen and then transfused back to the patient. Two months later, no tumor was found and no recurrence occurred in the following 22 months

BCR and TCR recognize antigens through antigen binding sites. The antigen binding sites of BCR are composed of three CDRs in the light chain and three CDRs in the light chain. The antigen binding sites of TCR are composed of a chain, B chain or C chain γ Each of the 8 chains consists of three CDRs

they are CDR1, CDR2 and CDR3, which are interposed between the four skeletal regions (FR), namely fr1cdr1fr2fr3-cdr3-fr4. CDR1, CDR2 and CDR3 are antigen binding sites, and the diversity of their sequences determines the diversity of antigen recognition

9. Are you sure it's TCR, not CR?
if it's Cr, it means it's copied from others, not original
