Artificial Tertiary Lymphoid Structures: Exploring Mesenchymal Stromal Cells as a Platform for Immune Niche Formation.

Constructing artificial tertiary lymphoid structures (TLSs) opens new avenues for advancing cancer immunotherapy and personalized medicine by creating controllable immune niches. Mesenchymal stromal cells (MSCs) offer an ideal stromal source for such constructs, given their potent immunomodulatory abilities and accessibility. In this study, we explored the potential of adipose-derived MSCs to adopt TLS-supportive phenotypes and facilitate lymphocyte organization.

[Dual inhibition of VEGF-A and angiopoietin-2 in the treatment of neovascular age-related macular degeneration and diabetic macular edema].

The introduction of faricimab, a drug targeting both vascular endothelial growth factor-A (VEGF-A) and angiopoietin-2, has enabled the implementation of the highly effective dual inhibition strategy in real clinical practice for patients with neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME), both previously treated with intravitreal injections and newly diagnosed. This article presents a series of 11 clinical cases involving patients with nAMD and DME who received loading doses of faricimab and continued ophthalmological observation. Among them, three patients with nAMD and two with DME were treatment-naïve, while the others were switched from alternative therapies to faricimab.

Assessment of the Safety of Anti-Salmonella Disinfectant for Veterinary Use Based on a Cocktail of Bacteriophages.

The toxicity and safety of a veterinary anti-salmonella disinfectant based on three highly virulent bacteriophage strains (titers 10 PFU/ml) were studied. Acute, chronic, and inhalation toxicity, as well as local irritancy of the disinfectant were evaluated on outbred white mice CD1 (n=65), Soviet chinchilla rabbits (n=20), and rats (n=20). No toxic effects of the disinfectant was observed after its intraperitoneal or intragastric administration to mice and intragastric administration to rats; in rabbits, application on the skin and eyes produced no local irritation effect.

Isolation and Characterization of Salmonella Bacteriophages as Potential Agents for Phage Therapy of Antibiotic-Resistant Intestinal Infections.

Two bacteriophages specifically active against to pathogenic strains of the Salmonella genus were isolated. The morphology of phage colonies (size, transparency, and shape of the plaque edge, and halo) and the spectrum of their lytic activity and interaction with microbial cells (adsorption rate, duration of the latency, and reproductive efficiency) were examined. Using genome-wide sequencing, we determined the taxonomic position of bacteriophages and verified the absence of unwanted genes encoding toxins, adhesins, and invasins, as well as pathogenicity islands responsible for antibiotic resistance.

Autophagy-Dependent Secretion: Crosstalk between Autophagy and Exosome Biogenesis.

The cellular secretome is pivotal in mediating intercellular communication and coordinating responses to stressors. Exosomes, initially recognized for their role in waste disposal, have now emerged as key intercellular messengers with significant therapeutic and diagnostic potential. Similarly, autophagy has transcended its traditional role as a waste removal mechanism, emerging as a regulator of intracellular communication pathways and a contributor to a unique autophagy-dependent secretome.
