Expression of Network Medicine-Predicted Genes in Human Macrophages Infected with .

spp. commonly infects phagocytic cells of the immune system, particularly macrophages, employing various immune evasion strategies that enable their survival by altering the intracellular environment. In mammals, these parasites establish persistent infections by modulating gene expression in macrophages, thus interfering with immune signaling and response pathways, ultimately creating a favorable environment for the parasite's survival and reproduction.

Rapid progression of CD8 and CD4 T cells to cellular exhaustion and senescence during SARS-CoV2 infection.

Risk factors for the development of severe COVID-19 include several comorbidities, but age was the most striking one since elderly people were disproportionately affected by SARS-CoV-2 infection. Among the reasons for this markedly unfavorable response in the elderly, immunosenescence and inflammaging appear as major drivers of this outcome. A finding that was also notable was that hospitalized patients with severe COVID-19 have an accumulation of senescent T cells, suggesting that immunosenescence may be aggravated by SARS-CoV-2 infection.

Obesity alters the macrophages' response to Leishmania major in C57BL/6 mice.

Obesity is a global pandemic associated with several comorbidities, such as cardiovascular diseases and type 2 diabetes. It is also a predisposing factor for infectious diseases, increasing mortality rates. Moreover, diet-induced obesity can cause metabolic fluctuations that affect macrophage differentiation in various organs.

Obesity-induced hyperglycemia impairs oral tolerance induction and aggravates food allergy.

Obesity and type 2 diabetes (T2D) have been found to be associated with abnormalities in several organs, including the intestine. These conditions can lead to changes in gut homeostasis, compromising tolerance to luminal antigens and increasing susceptibility to food allergies. The underlying mechanisms for this phenomenon are not yet fully understood.

The Therapeutic Effect of Phosphopeptide P140 Attenuates Inflammation Induced by Uric Acid Crystals in Gout Arthritis Mouse Model.

Gout is a painful form of inflammatory arthritis characterized by the deposition of monosodium urate (MSU) crystals in the joints. The aim of this study was to investigate the effect of peptide P140 on the inflammatory responses in crystal-induced mouse models of gout and cell models including MSU-treated human cells. Injection of MSU crystals into the knee joint of mice induced neutrophil influx and inflammatory hypernociception.

Possible Benefits of for Obesity-Associated Gut Disorders.

Metabolic disorders are an increasing concern in the industrialized world. Current research has shown a direct link between the composition of the gut microbiota and the pathogenesis of obesity and diabetes. In only a few weeks, an obesity-inducing diet can lead to increased gut permeability and microbial dysbiosis, which contributes to chronic inflammation in the gut and adipose tissues, and to the development of insulin resistance.

Obesity impairs resistance to Leishmania major infection in C57BL/6 mice.

An association between increased susceptibility to infectious diseases and obesity has been described as a result of impaired immunity in obese individuals. It is not clear whether a similar linkage can be drawn between obesity and parasitic diseases. To evaluate the effect of obesity in the immune response to cutaneous Leishmania major infection, we studied the ability of C57BL/6 mice fed a hypercaloric diet (HSB) to control leishmaniasis.

High sugar and butter (HSB) diet induces obesity and metabolic syndrome with decrease in regulatory T cells in adipose tissue of mice.

Objective: The purpose of the study was to develop a novel diet based on standard AIN93G diet that would be able to induce experimental obesity and impair immune regulation with high concentrations of both carbohydrate and lipids.

Methods: To compare the effects of this high sugar and butter (HSB) diet with other modified diets, male C57BL/6 mice were fed either mouse chow, or AIN93G diet, or high sugar (HS) diet, or high-fat (HF) diet, or high sugar and butter (HSB) diet for 11 weeks ad libitum. HSB diet induced higher weight gain.
