The phospho-sphingolipid, ceramide 1-phosphate (C1P), has long been implicated as a dynamic bioactive agent. Over two decades of research has begun to characterize various regulatory roles for C1P from mammalian inflammatory response and wound healing to cellular proliferation and survival. As a metabolite of the intricately balanced "sphingolipid rheostat", C1P stands as a crucial physiological regulator of both upstream and downstream mechanisms. This chapter serves as an overview of established and implicated roles for C1P in cellular processes vital to diseases and mammalian physiology. Additionally, we discuss potential clinical roles for C1P in cancer treatment, wound therapy, and pre-disease diagnosis. While many questions remain regarding C1P metabolism and the extent of signaling factors targeted by this bioactive lipid, new technologies and methodologies show great promise to discern key targets, signaling pathways, and physiologies regulated by C1P.

Sphingolipids modulate redox signalling during human sperm capacitation.

Study Question: What role do sphingolipids have in mediating human sperm capacitation?
Summary Answer: Sphingosine 1-phosphate (S1P) mediates the acquisition of fertilizing competency in human spermatozoa by engaging with its Gi-coupled receptor S1PR1 and promoting production of reactive oxygen species such as nitric oxide and superoxide anion.
What Is Known Already: Bioactive sphingolipids, such as S1P, are fundamental for regulating numerous physiological domains and processes, such as cell membranes and signalling, cell death and proliferation, cell migration and invasiveness, inflammation, and central nervous system development.
Study Design, Size, Duration: Semen samples were obtained from a cohort of 10 healthy non-smoking volunteers (18-30 years old) to investigate the role of S1P in sperm.
Altered sphingolipid profile in response to skeletal muscle injury in a mouse model of type 1 diabetes mellitus.

A complication of type 1 diabetes mellitus (T1DM) is diabetic myopathy that includes reduced regenerative capacity of skeletal muscle. Sphingolipids are a diverse family of lipids with roles in skeletal muscle regeneration. Some studies have found changes in sphingolipid species levels in T1DM, however, the effect of T1DM on a sphingolipid panel in regenerating skeletal muscle has not been examined.

Article Synopsis
- M is a crucial structural protein in coronaviruses, specifically SARS-CoV-2, playing a key role in forming infectious virus particles and existing in two conformational states.
- The study identifies a specific interaction between the M protein and a type of lipid (ceramide-1-phosphate) that influences M's structure and its ability to facilitate virus assembly.
- Disrupting this lipid-protein interaction impacts M's localization and its interactions with other viral proteins, ultimately hindering the virus's ability to enter host cells.

Abnormal lipid metabolism plays an important role in cancer development. In this study, nontargeted lipidomic study on 230 tissue specimens from 79 nonsmall cell lung cancer (NSCLC) patients was conducted using ultraperformance liquid chromatography-high-resolution mass spectrometry (UPLC-HRMS). Downregulation of sphingosine and medium-long-chain ceramides and short-medium-chain acylcarnitine, upregulation of long-chain acylcarnitine C20:0, and enhanced histamine methylation were revealed in NSCLC tissues.

Sphingolipids, crucial components of cellular membranes, play a vital role in maintaining cellular structure and signaling integrity. Disruptions in sphingolipid metabolism are increasingly implicated in cancer development. Key bioactive sphingolipids, such as ceramides, sphingosine-1-phosphate (S1P), ceramide-1-phosphate (C1P), and glycosphingolipids, profoundly impact tumor biology.
