Lipidomics, a subfield of metabolomics, provides comprehensive analysis of lipids in biological systems and is essential for biomedical research, driven by advances in analytical technologies. Lipids are crucial biomolecules in cellular functions and have been increasingly recognized for their role in physiological and pathological processes. This study focuses on advanced strategies for the development, validation, and implementation of untargeted lipidomics methods in human plasma and extracellular vesicles (EVs) using liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Background: Elevated levels of prokineticin-2 (PK2), regarded as a protein involved in modulating immune/inflammatory responses, have been detected in the substantia nigra, serum, and olfactory neurons of Parkinson's disease (PD) patients. Of note, emerging evidence suggests that gut alterations, including dysbiosis and enteric inflammation, play a role in PD via the gut-brain axis.

Objectives: Our goal was to investigate the expression of PK2 in colonic biopsies of PD patients.

Snake venoms are complex mixtures majorly composed of proteins with well-studied biological effects. However, the exploration of non-protein components, especially lipids, remains limited despite their potential for discovering bioactive molecules. This study compares three liquid-liquid lipid extraction methods for both chemical and biological analyses of Bothrops moojeni snake venom.

Although perianal Crohn's disease (PCD) is highly associated with the exacerbated inflammation, the molecular basis and immunological signature that distinguish patients who present a history of perianal lesions are still unclear. This paper aims to define immunological characteristics related to PCD. In this cross-sectional observational study, we enrolled 20 healthy controls and 39 CD patients.

Cancer treatment is challenged due to immunosuppressive inflammatory tumour microenvironment (TME) caused by infiltration of tumour-promoting and inhibition of tumour-inhibiting immune cells. Here, we report the engineering of chimeric nanomicelles (NMs) targeting the cell proliferation using docetaxel (DTX) and inflammation using dexamethasone (DEX) that alters the immunosuppressive TME. We show that a combination of phospholipid-DTX conjugate and PEGylated-lipid-DEX conjugate can self-assemble to form sub-100 nm chimeric NMs (DTX-DEX NMs).
