Studies show that highly diluted medications demonstrate benefits in treating infections, constituting an alternative for their treatment. The present study evaluated the effects of Lycopodium clavatum, dynamization 13c, in Wistar rats infected with T. cruzi. In this study 42 male rats were intraperitoneally inoculated with T. cruzi - Y strain and allocated into groups: IC (infected control group) and Ly (treated with L. clavatum 13c). The cytokines dosage (IFN-γ, IL-12, IL-10, IL-4), quantification and morphometry of myenteric neurons were evaluated. The treatment with L. clavatum modifies the immune response, with increase of IFN-γ on day 10 a.i. and IL-12 on day 24 a.i., decrease of IL-10 concentration on day 10 a.i. and subsequent increase of this cytokine and IL-4 on day 24 a.i., affording a bigger number of myenteric neurons compared to IC group. Thus, L. clavatum 13c promoted on rats infected with T. cruzi a beneficial immunomodulatory action reducing the pathogenic progression of digestive Chagas disease.

Mesenchymal stromal/stem cells (MSCs) are promising candidates for regenerative medicine owing to their self-renewal properties, multilineage differentiation, immunomodulatory effects, and angiogenic potential. MSC spheroids fabricated by 3D culture have recently shown enhanced therapeutic potential. MSC spheroids create a specialized niche with tight cell-cell and cell-extracellular matrix interactions, optimizing their cellular function by mimicking the in vivo environment.

Atopic dermatitis (AD) is a chronic, inflammatory skin condition characterized by severe pruritus and recurrent flare-ups, significantly impacting patients' quality of life. Current treatments, such as corticosteroids and immunomodulators, often provide symptomatic relief but can lead to adverse effects with prolonged use. Seaweed, a sustainable and nutrient-dense resource, has emerged as a promising alternative due to its rich bioactive compounds-polysaccharides, phlorotannins, polyphenols, and chlorophyll-that offer anti-inflammatory, antioxidant, and immunomodulatory properties.

Mycotoxin occurrence in food worldwide is estimated to increase due to climate change. Moreover, studies on how these food contaminants interfere with medications and especially anticancer therapies are rare. With the rise of anticancer immunotherapies, particularly mycotoxins with immunomodulatory activity, such as alternariol (AOH) or deoxynivalenol (DON), are of great concern.
