🔴 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.

At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. "There is a significant risk of insider threat or hacking of Telegram systems that could expose all of these chats to the Russian government," said Eva Galperin with the Electronic Frontier Foundation, which has called for Telegram to improve its privacy practices. And while money initially moved into stocks in the morning, capital moved out of safe-haven assets. The price of the 10-year Treasury note fell Friday, sending its yield up to 2% from a March closing low of 1.73%. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. Meanwhile, a completely redesigned attachment menu appears when sending multiple photos or vides. Users can tap "X selected" (X being the number of items) at the top of the panel to preview how the album will look in the chat when it's sent, as well as rearrange or remove selected media.
