The class F of G protein-coupled receptors (GPCRs) consists of 10 Frizzleds (FZD_1–10) and Smoothened (SMO). FZDs bind and are activated by secreted lipoglycoproteins of the Wingless/Int-1 (WNT) family, and SMO is indirectly activated by the Hedgehog (Hh) family of morphogens acting on the transmembrane protein Patched. The advance of our understanding of FZDs and SMO as dynamic transmembrane receptors and molecular machines, which emerged during the past 14 years since the first-class F GPCR IUPHAR nomenclature report, justifies an update. This article focuses on the advances in molecular pharmacology and structural biology providing new mechanistic insight into ligand recognition, receptor activation mechanisms, signal initiation, and signal specification. Furthermore, class F GPCRs continue to develop as drug targets, and novel technologies and tools such as genetically encoded biosensors and CRISP/Cas9 edited cell systems have contributed to refined functional analysis of these receptors. Also, advances in crystal structure analysis and cryogenic electron microscopy contribute to the rapid development of our knowledge about structure-function relationships, providing a great starting point for drug development. Despite the progress, questions and challenges remain to fully understand the complexity of the WNT/FZD and Hh/SMO signaling systems.

Significance Statement

The recent years of research have brought about substantial functional and structural insight into mechanisms of activation of Frizzleds and Smoothened. While the advance furthers our mechanistic understanding of ligand recognition, receptor activation, signal specification, and initiation, broader opportunities emerge that allow targeting class F GPCRs for therapy and regenerative medicine employing both biologics and small molecule compounds.

Both preclinical and clinical studies implicate functional impairments of several neuroactive metabolites of the kynurenine pathway (KP), the major degradative cascade of the essential amino acid tryptophan in mammals, in the pathophysiology of neurologic and psychiatric diseases. A number of KP enzymes, such as tryptophan 2,3-dioxygenase (TDO2), indoleamine 2,3-dioxygenases (IDO1 and IDO2), kynurenine aminotransferases (KATs), kynurenine 3-monooxygenase (KMO), 3-hydroxyanthranilic acid oxygenase (3-HAO), and quinolinic acid phosphoribosyltransferase (QPRT), control brain KP metabolism in health and disease and are therefore increasingly considered to be promising targets for the treatment of disorders of the nervous system. Understanding the distribution, cellular expression, and regulation of KP enzymes and KP metabolites in the brain is therefore critical for the conceptualization and implementation of successful therapeutic strategies.

Significance Statement

Studies have implicated the kynurenine pathway of tryptophan in the pathophysiology of neurologic and psychiatric diseases. Key enzymes of the kynurenine pathway regulate brain metabolism in both health and disease, making them promising targets for treating these disorders. Therefore, understanding the distribution, cellular expression, and regulation of these enzymes and metabolites in the brain is critical for developing effective therapeutic strategies. This review endeavors to describe these processes in detail.:

As a group of friends circled a hearse, chants were heard. Then, they stopped and bowed to the portrait displayed at the front of the vehicle. This was not a typical Buddhist funeral, but rather the unconventional birthday celebration of a funeral director, reported Shin Min Daily News. According to the Chinese evening daily, a video circulating online showed the friends chanting a birthday song. The hearse's interior had been decorated with balloons and a birthday banner, with the man even laying inside for photos. The clip garnered criticism from netizens, with some deeming it overboard and disrespectful to the funeral industry. In an interview with Shin Min, director of Xin An Funeral Services Chen Weisong (transliteration) explained that he had celebrated his birthday at the company's premises with his friends and family last week. Halfway through the performances by singers, his employees and business partners had surprised him with the birthday-themed hearse bearing his portrait. Chen told 8world he was not angry and did not think it was taboo. "I was too embarrassed to turn down their gesture," he said.

In the wake of the reelection of Donald Trump, some of the richest people in the world saw their net worths soar as stock prices rapidly shot up. “What was different about this election was how central billionaires were in the entire political discourse,” says The Lever's David Sirota, who joins Democracy Now! to discuss the outsized role of the super-rich in U.S politics, pointing out that both Trump and Kamala Harris campaigned heavily with billionaires, including Elon Musk and Mark Cuban. “These people are not giving money simply out of the goodness of their hearts. They want things. They have policy demands,” Sirota says. “The investors, the donors, like billionaires, are looking for a return on their investment.” Sirota, who previously worked as a communications adviser and speechwriter for the Bernie Sanders presidential campaign, also explains how Elon Musk's influence on Trump’s campaign is a preview of the power he could wield if he ends up appointed to the Trump administration.

Barb E. asked for Navy icing:

She got it.

 

Cindy M. just wanted the initial "G" for her 14-year-old daughter - but I guess that was TOO simple?

 

Jen and Pete asked the bakery to include paper plates and plastic silverware.

 

Pauline ordered a cake that said, "I hate you for leaving!"

...but sure, that's close enough.

 

Holli T. wanted the number 10 written as a number: "you know, with double digits."

Part of me hopes Alexis gets a great nickname outta this.

 

Charli C. made the mistake of telling her bakery who the cake was for:

THANKS, GUYS.

 

And finally, Jared C. asked for rainbow sprinkles.

How do you mess up rainbow sprinkles?

Oh, like this:

Thanks to Barb E., Cindy M., Jen & Pete, Pauline R., Holli T., Charli C., & Jared C. for the head bangers.
