Summary: This study developed a mouse model with selective knockout of TLQP-21 neuropeptide and provided multiple independent validations. The DTLQP-21 mice showed no gross behavioral and metabolic abnormalities but exhibited a unique metabolic phenotype characterized by temperature-dependent resistance to diet-induced obesity and activation of brown adipose tissue. This research is important for understanding the necessary role of TLQP-21 in physiology and disease, as well as testing novel antibodies or immunoassays targeting TLQP-21.

Summary: Marine-derived fungi are unique sources of bioactive secondary metabolites, particularly peptides, with diverse structures and biological activities. This review summarizes the literature on marine fungal peptides from January 1991 to June 2023, covering their chemical characteristics, sources, and biological and pharmacological activities. Among 30 genera, Aspergillus was found to produce the highest number of peptides, followed by Penicillium, Acremonium, Eurotium, Trichoderma, Simplicillium, and Beauveria. The predominant activity of the reported marine peptides was cytotoxicity against human cancer cell lines, followed by antibacterial, antifungal, antiviral, anti-inflammatory, and enzyme inhibition activities.

Summary: TLQP-21 is a neuropeptide derived from the VGF precursor protein and has pleiotropic roles in regulating metabolism, nociception, and microglial functions. TLQP-21 acts through several receptors, with C3aR being the most commonly reported. However, its activity in immune cells, which express C3aR, remains understudied. This study found that TLQP-21 induced ERK signaling in human and mouse macrophages, with mouse TLQP-21 being more potent than the human counterpart. These findings suggest a significant discrepancy in TLQP-21 C3aR activity between human and murine receptors in immune cells.

Summary: In this study, a Temporin L analogue, [Nle(1), dLeu(9), dLys(10)]TL, was developed, which exhibited more efficient antimicrobial activity and induced membrane destabilization and deformation in bacterial membranes. The modification increased the peptide's hydrophobicity without affecting its anti-inflammatory activity compared to the lead peptide.

Summary: Head and neck squamous cell carcinoma (HNSCC) originates from the mucosal epithelium and laryngeal squamous cell carcinoma (LSCC) is a subtype of HNSCC. This study focuses on the role of the Survival Motor Neuron (SMN) protein in LSCC and explores its impact on cancer-related behaviors. The study also reveals a physical interaction between SMN and the epidermal growth factor receptor (EGFR) in LSCC. Overall, this study highlights SMN as a potential therapeutic target for LSCC and other subtypes of HNSCC.

Summary: Olfactory capacity decline is associated with aging and may indicate the early stages of neurodegenerative diseases such as Alzheimer's and Parkinson's disease. Understanding the role of olfaction in these diseases is of great interest to scientists. Olfactory impairment could potentially serve as an early marker for neurodegenerative diseases, but further research is needed to fully understand the underlying mechanisms.

Summary: Obstructive sleep apnea syndrome (OSAS) is a disease characterized by intermittent hypoxia (IH) during sleep due to recurrent upper airway obstruction. The associated oxidative stress (OS) leads to various complications that affect both sleep-wake rhythm and systemic functions. This literature review investigates the molecular changes, diagnostic markers, and potential medical therapies for OSAS. The findings suggest that IH increases oxygen free radicals (ROS) and impairs antioxidant capacities, resulting in endothelial dysfunction, osteoporosis, systemic inflammation, increased cardiovascular risk, pulmonary remodeling, and neurological alterations in OSAS patients. The most promising pharmacological therapies include N-acetylcysteine (NAC), Vitamin C, Leptin, Dronabinol, or Atomoxetine + Oxybutynin, but further research is needed. Continuous positive airway pressure (CPAP) remains the approved therapy for reversing most molecular changes, while future drugs may target the remaining dysfunctions.

Summary: Primary Sjogren's Syndrome (pSS) is an autoimmune disease that affects the lacrimal and salivary glands, resulting in reduced secretion and symptoms like dry mouth and dry eyes. This study found decreased levels of substance P (SP) and increased levels of NK1R in the minor salivary glands of pSS patients, suggesting their involvement in the impaired salivary secretion. The increase in apoptosis in pSS patients was also related to JNK phosphorylation.

Summary: This pilot study aimed to investigate the impact of COVID-19 on brain-derived neurotrophic factor (BDNF), matrix metalloproteinases (MMP) 2 and 9, and neurofilament light chain (NFL) pathways in aged men. The results showed disrupted serum BDNF, NFL, and MMP-2 presence in severe or fatal COVID-19 cases, along with changes in routine blood parameters. The ratio of MMPs (2 and 9) to BDNF and NFL was found to be a useful tool for predicting fatal outcomes of COVID-19.

Summary: Alcohol consumption is associated with oxidative stress and an increased risk of upper aero-digestive tract (UADT) carcinoma. Microorganisms in the oral cavity can metabolize ethanol and form acetaldehyde, a carcinogenic metabolite. A study was conducted on UADT cancer patients to estimate their alcohol consumption and analyze the presence of acetaldehyde-producing bacteria. The study found that heavy drinkers had a higher presence of these bacteria, which correlated with increased oxidative stress.

Summary: Fetal alcohol spectrum disorder (FASD) is a set of conditions caused by prenatal alcohol exposure. It affects an estimated 2% to 5% of people in the United States and Western Europe. The exact mechanism of alcohol's impact on fetal development is unclear, but it involves decreased glutathione peroxidase action and increased production of reactive oxygen species (ROS), leading to oxidative stress. We report a case of a mother who abused alcohol, smoked cigarettes, and used cocaine during pregnancy, resulting in her newborn being diagnosed with FAS. The study highlights the importance of intensive hospital monitoring and controls for FASD cases.

Summary: Programmed cell death ligand-1 (PD-L1) binds PD-1 on CD8+ lymphocytes, inhibiting their cytotoxic action. Its aberrant expression by head and neck squamous cell carcinoma (HNSCC) cells leads to immune escape. Pembrolizumab and nivolumab, two humanized monoclonal antibodies against PD-1, have been approved in HNSCC treatment, but similar to 60% of patients with recurrent or metastatic HNSCC fail to respond to immunotherapy and only 20 to 30% of treated patients have long-term benefits.

Summary: The potential use of antioxidants in preventing second primary cancers in HNSCC patients has been explored. Although a low dietary intake of antioxidants has been linked to an increased cancer risk, it has been found that the antioxidants tested so far are not effective in preventing second primary tumors in HNSCC patients.

Summary: OSAS, affecting 2% of men and 4% of women of middle age, is a major public health problem due to its possible cardiovascular, metabolic, and cerebrovascular complications. The correlation between OSAS and hearing loss is demonstrated, with oxidative stress as the main pathogenetic mechanism of damage. CPAP shows no effects on hearing function. Further studies are needed to evaluate extended high frequencies, vocal audiometry in noisy environments, and potential biomarkers.

Summary: Sudden sensorineural hearing loss (SSHL) is a debilitating condition that affects a patient's quality of life, and its etiology remains mostly unknown. COVID-19 infection has been associated with various ENT manifestations, including throat pain, headache, nasal obstruction, and tonsil enlargement. This study reports a case of post-COVID-19 SSHL and explores the potential of serum neurofilament light (NfL) as a biomarker for neuronal damage.
