A fluorescent photoaffinity probe for formyl peptide receptor 1 labelling in living cells

About this article

The paper explores developing a chemical tool to label formyl peptide receptor 1 (FPR1) in cells. FPR1 is a sensor in the human innate immune system, which is our body’s ancient first-line response system to detect pathogens. FPR1 is found in our immune cells; it helps these cells move towards sites of infection by sensing peptides released from bacteria.

However, the role of FPR1 is not so simple. FPR1 has been reported in other cells, such as those lining our mucous membranes (gut, lungs etc.), where it presumably comes into contact with many of our friendly bacteria without causing widespread immune activation. This family of proteins (FPRs1-3) can recognise very different molecules, and how this occurs is only beginning to be explored. FPRs can also cause and suppress inflammation and have been linked to numerous diseases (cancer, autoimmune disease). However, it’s unclear how this occurs and how we might modulate it to treat diseases.

In this paper, we designed a tool to label or tag FPR1 with a dye so we can see this sensor on the surface of cells. Our tool also allows us to detect inhibitors that bind FPR1. A key feature of it, is that it permanently labels FPR1. We expect it will be useful to understand the fundamentals of FPR1 biology and explore how we can treat diseases through molecules that activate or repress this protein.

SREBP activation contributes to fatty acid accumulations in necroptosis

About this article:

Necroptosis is a type of programmed cell death that is accompanied by extensive inflammatory activity. Previously, it has been shown that lipids accumulate in this process, and the accumulation exacerbates the membrane permeability and cell death in necroptosis.

However, the mechanisms that result in the accumulation of these lipids are unknown.

In this work, the authors used a global transcriptomics approach. They investigated the changes in the expression of proteins involved in lipid biosynthesis and transport to identify upstream mechanisms that cause lipid accumulation in necroptosis. Such a transcriptomics approach combined with further targeted experiments revealed the activation of a key regulatory mechanism of lipid production, namely sterol regulatory element binding proteins.

The authors showed that modulating the activation of sterol regulatory element binding proteins impacts necroptotic phenotype, demonstrating the functional role of these proteins in the accumulation of toxic lipids in necroptosis. Moreover, these results provide insights into mechanisms that regulate lipid production in cell death.

Call for papers – Molecular and nanotheranostics

 

A slide summarising the information in this blog post.

RSC Chemical Biology and RSC Medicinal Chemistry are delighted to welcome papers for an online themed collection on ‘Molecular and nanotheranostics’, guest edited by Prof. Thimmaiah Govindaraju (Jawaharlal Nehru Centre for Advanced Scientific Research, India).

 Over a decade of intense research has positioned theranostics as a promising and integrated approach to advance biomedical research and medicine. The term theranostics essentially conveys the idea of combining therapeutic and diagnostic modalities to provide a holistic solution for disease management. Theranostics is also referred to as diagnostic therapy, wherein molecular and/or material tools for non-invasive treatment and diagnostic imaging are strategically embedded into a single system. For instance, multifunctional diagnostic platforms carrying therapeutic and target tracking agents offer remedial effects and imaging of markers in tissue or organs, which is used to assess disease staging, treatment planning and therapeutic efficacy.

Theranostics has the potential to revolutionize the practice and adaptation of personalized medicine to tackle chronic disease conditions like cancer and neuronal disorders. Generally, radiopharmaceutical, nano and macromolecular systems armed with tools to detect, treat, track, and image biomolecular targets in real-time have been employed as theranostics to effectively manage disease progression and cure.

In recent years, the field has witnessed the emergence of small molecules or small molecular conjugates as theranostic tools. This special collection in RSC Chemical Biology and RSC Medicinal Chemistry intends to cover and highlight advancements in molecular theranostics with particular emphasis on chemical biology of molecular design of theranostic tools and their selective interaction with the biomolecular targets to image and ameliorate the pathological conditions. This themed collection is anticipated to catalyze the development of precision theranostics as advanced and personalizable tools in chemical biology and modern medicine.

 The deadline for submissions has been extended to 30 June 2023.

 Articles can be submitted via  the appropriate journal’s website, where you can find details on their scopes and focus. RSC Chemical Biology accepts exceptionally significant and breakthrough findings of interest to the chemical biology community, while RSC Medicinal Chemistry publishes significant research in medicinal chemistry and related drug discovery science.
