Prodrugs are bioreversible drug derivatives which are metabolized into a pharmacologically active drug following chemical or enzymatic modification. This approach is designed to overcome several obstacles that are faced by the parent drug in physiological conditions that include rapid drug metabolism, poor solubility, permeability, and suboptimal pharmacokinetic and pharmacodynamic profiles. These suboptimal physicochemical features can lead to rapid drug elimination, systemic toxicities, and limited drug-targeting to disease-affected tissue. Improving upon these properties can be accomplished by a prodrug design that includes the careful choosing of the promoiety, the linker, the prodrug synthesis, and targeting decorations. We now provide an overview of recent developments and applications of prodrugs for treating neurodegenerative, inflammatory, and infectious diseases. Disease interplay reflects that microbial infections and consequent inflammation affects neurodegenerative diseases and vice versa, independent of aging. Given the high prevalence, personal, social, and economic burden of both infectious and neurodegenerative disorders, therapeutic improvements are immediately needed. Prodrugs are an important, and might be said a critical tool, in providing an avenue for effective drug therapy.

Evaluation of Plasma Neurodegenerative Biomarkers for Diagnosing Minimal Hepatic Encephalopathy and Predicting Overt Hepatic Encephalopathy in Chinese Patients with Hepatic Cirrhosis.

Department of Infectious Diseases, Tongji Hospital, Tongji Medical College and State Key Laboratory for Diagnosis and Treatment of Severe Zoonotic Infectious Diseases, Huazhong University of Science and Technology, Wuhan, Hubei, China.
Background And Aims: The performance of neurodegenerative biomarkers-neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), tau, and ubiquitin carboxy-terminal hydrolase L1 (UCHL1)-in diagnosing minimal hepatic encephalopathy (MHE) has not been systematically evaluated, simultaneously, nor have their associations with the development of overt hepatic encephalopathy (OHE). This study aimed to evaluate the performance of plasma NfL, GFAP, tau, and UCHL1 in diagnosing MHE and predicting the development of OHE in Chinese patients with hepatic cirrhosis.
Methods: In this prospective study, 124 patients with hepatic cirrhosis were recruited.
The periplasmic protein HslJ is the first-line of defense against oxidative stress in Acinetobacter baumannii.

Department of Human Sciences and Quality of Life Promotion, San Raffaele University, 00166, Rome, Italy.
Background: Acinetobacter baumannii poses a significant threat globally, causing infections primarily in healthcare settings, with high mortality rates. Its adaptability to antibiotic resistance and tolerance to various stresses, including reactive oxygen species (ROS), contribute to its persistence in healthcare environments. Previous evidence suggested that the periplasmic heat shock protein, HslJ-like protein (ABUW_2868), could be involved in oxidative stress defense in A.

Extracellular vesicles (EVs) are nanoscale, membrane-enclosed structures released by cells into the extracellular milieu. These vesicles encapsulate a diverse array of molecular constituents, including nucleic acids, proteins, and lipids, which provide insights into the physiological or pathological conditions of their parent cells. Despite their potential, the study of EV-derived DNA (EV-DNA) has gathered relatively limited attention.

January 2025
İzmir Tınaztepe University, Faculty of Medicine, Department of Infectious Diseases and Clinical Microbiology, İzmir, Türkiye.
Background Objectives: This study was compared the Borrelia antibodies and chemokine ligand 13 (CXCL13) levels in cerebrospinal fluid (CSF) samples from cases diagnosed with relapsing-remitting multiple sclerosis (RRMS), radiologically isolated syndrome (RIS), and pseudotumour cerebri (PTC).
Methods: A total of 43 CSF samples were collected from patients diagnosed with RRMS, RIS and PTC. We prospectively investigated Borrelia IgG and IgM antibodies in the CSF samples of the cases by enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) method, and CXCL13 levels by ELISA.
The Beneficial Effects of Lactobacillus Strains on Gut Microbiome in Alzheimer's Disease: A Systematic Review.

January 2025
Neuroimmunology Laboratory, School of Medicine, Western Sydney University, Campbelltown, NSW 2560, Australia.
Background/objectives: Growing evidence suggests that the gut-brain axis influences brain function, particularly the role of intestinal microbiota in modulating cognitive processes. Probiotics may alter brain function and behavior by modulating gut microbiota, with implications for neurodegenerative diseases like Alzheimer's disease (AD). The purpose of this review is to systematically review the current literature exploring the effects of probiotic supplementation on gut microbiota and cognitive function in AD and mild cognitive impairment (MCI).
