Purpose: Preeclampsia (PE) is a pregnancy-specific syndrome with a complex, yet elusive, etiology. The production of a variety of factors probably implicated in diverse pathways may trigger endothelial dysfunction leading to PE pathogenesis. The aim of the present study was to investigate and compare the concentrations of leptin and interferon-gamma-inducible protein-10 (IP-10), factors characterized by inflammatory, immunomodulatory and angiogenic activities, and to evaluate their possible interaction in women with normotensive pregnancy and PE.
Methods: The study was carried out on a total of 58 pregnant women, 29 women with PE and 29 controls. Serum leptin and IP-10 levels were determined by enzyme-linked immunosorbent assay.
Results: Serum leptin levels were significantly increased in women with PE compared to controls and this difference was stronger in women with severe PE (p < 0.001). Although IP-10 serum concentrations were elevated in our preeclamptic women, this difference was not statistically significant. No correlation was found between leptin and IP-10.
Conclusions: The results of the present study support a significant role of leptin in PE; however, this association was independent from serum IP-10 levels, suggesting that there is no crucial interplay between these two proteins in PE.

Association of circulating biomarkers with illness severity measures differentiates myalgic encephalomyelitis/chronic fatigue syndrome and post-COVID-19 condition: a prospective pilot cohort study.
J Transl Med
April 2024
Division of Rheumatology, Research Unit in ME/CFS and Long COVID, Vall d'Hebron Research Institute, Universitat Autònoma de Barcelona, Barcelona, 08035, Spain.
Background: Accumulating evidence suggests that autonomic dysfunction and persistent systemic inflammation are common clinical features in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID. However, there is limited knowledge regarding their potential association with circulating biomarkers and illness severity in these conditions.
Methods: This single-site, prospective, cross-sectional, pilot cohort study aimed to distinguish between the two patient populations by using self-reported outcome measures and circulating biomarkers of endothelial function and systemic inflammation status.
Anti-Inflammatory and Cortical Responses after Transcranial Direct Current Stimulation in Disorders of Consciousness: An Exploratory Study.
J Clin Med

Department of Neuroscience and Rehabilitation, Ferrara University, 44121 Ferrara, Italy.
Disorders of consciousness (DoC) due to severe traumatic brain injury (TBI) are associated with severe disability and an alteration of cortical activation, angiogenesis, and inflammation, which are crucial elements for behavioural recovery. This exploratory study aimed to evaluate anti-inflammatory and cortical responses after transcranial direct current stimulation (tDCS) in traumatic prolonged disorders of consciousness. Ten minimally conscious state (MCS) patients underwent ten sessions of anodal tDCS (five sessions/week, two weeks, 40 min/session) on the primary motor cortex bilaterally.

Article Synopsis
- Pulmonary Langerhans cell histiocytosis (PLCH) is a rare interstitial lung disease primarily associated with smoking, diagnosed through a surgical lung biopsy and differentiation from other ILDs.
- A study analyzed bronchoalveolar lavage (BAL) samples from 36 ILD patients to identify unique cytokine and chemokine profiles that could help distinguish PLCH from other smoking-related ILDs and idiopathic pulmonary fibrosis (IPF).
- Significant differences in 32 cytokines/chemokines were observed, with PCA showing distinct clustering of patients, and a random forest model successfully differentiated PLCH from other ILDs based on immune profiles.
Benznidazole treatment decreases IL-6 levels in Trypanosoma cruzi-infected human adipocytes differentiated from adipose tissue-derived stem cells.

Background: Trypanosoma cruzi, which causes Chagas disease (CD), is a versatile haemoparasite that uses several strategies to evade the host's immune response, including adipose tissue (AT), used as a reservoir of infection. As it is an effective barrier to parasite evasion, the effectiveness of the drug recommended for treating CD, Benznidazole (BZ), may be questionable.
Objective: To this end, we evaluated the parasite load and immunomodulation caused by BZ treatment in the culture of adipocytes differentiated from human adipose tissue-derived stem cells (ADSC) infected with T.
Diabetes diminishes muscle precursor cell-mediated microvascular angiogenesis.

The skeletal muscles of Type II diabetic (T2D) patients can be characterized by a reduced vessel density, corresponding to deficiencies in microvascular angiogenesis. Interestingly, T2D also inhibits the function of many myogenic cells resident within skeletal muscle, including satellite cells, which are well-known for the role they play in maintaining homeostasis. The current study was undertaken to gain a better understanding of the mechanisms whereby satellite cell progeny, muscle precursor cells (MPCs), influence microvascular angiogenesis.
