🔴 Oneway for Don't eat me signal is an interaction between CD47 and SIRPalpha. SIRP family has three different subtypes include Alpha, Beta, and Gamma.
🟠 In cancer cells interaction between SIRPalpha and CD inhibits macrophages to select cancer cells and macrophage phagocytosis and also this mechanism help cancer cells to evade the immunity.
🟡 Many studies shown that overexpression and higher levels of CD47 in tumor cells surface than non-malignant cells.
🟢 By exploiting the "Don't eat me" signal, cancer cells utilize CD47's overexpression to evade immune cell surveillance and clearance, making CD47 a potential target for novel anti-tumor therapies.

Founder Pavel Durov says tech is meant to set you free "Russians are really disconnected from the reality of what happening to their country," Andrey said. "So Telegram has become essential for understanding what's going on to the Russian-speaking world." At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised. The message was not authentic, with the real Zelenskiy soon denying the claim on his official Telegram channel, but the incident highlighted a major problem: disinformation quickly spreads unchecked on the encrypted app. WhatsApp, a rival messaging platform, introduced some measures to counter disinformation when Covid-19 was first sweeping the world.
