The Role of Macrophages in Cancer: From Basic Research to Clinical Applications

open access: yesMedComm, Volume 7, Issue 1, January 2026.
Monocytes infiltrate the tumor microenvironment (TME) and differentiate into macrophages, which polarize into proinflammatory, antitumor M1 cells or immunosuppressive, protumor M2 cells. Within the TME, M2‐type tumor‐associated macrophages (TAMs) predominate and drive tumor growth, angiogenesis, and metastasis. Therapeutic strategies therefore focus on

X-ray studies of enzymes that interact with penicillins. [PDF]

open access: yes, 1998
The technique of X-ray diffraction has been successfully applied to enzymes associated with peptidoglycan biosynthesis. The technique has taught us a great deal about the structures and catalytic mechanisms of penicillin-binding proteins and beta ...

Effects of Heterologous Protein Substitutions of Fishmeal on the Culture of the Chinese Soft‐Shelled Turtle (Pelodiscus sinensis): A Review and Meta‐Analysis

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
With the global aquaculture industry growing rapidly, fishmeal (FM) occupies an important position in aquatic animal nutrition as a traditional feed ingredient, but its production is facing rising costs and sustainability challenges, making the search for high‐quality heterologous proteins particularly essential.

In vivo functional and molecular characterization of the Penicillin-Binding Protein 4 (DacB) of Pseudomonas aeruginosa [PDF]

open access: yes, 2016
Background: Community and nosocomial infections by Pseudomonas aeruginosa still create a major therapeutic challenge. The resistance of this opportunist pathogen to β-lactam antibiotics is determined mainly by production of the inactivating enzyme AmpC ...

Amyloid Beta in Alzheimer's Disease: Mechanisms, Biomarker Potential, and Therapeutic Targets

open access: yesCNS Neuroscience &Therapeutics, Volume 31, Issue 12, December 2025.
The limited clinical efficacy of anti‐Aβ antibodies has challenged the Aβ hypothesis, compelling the integration of key mechanisms—including neuroinflammation, mitochondrial dysfunction, oxidative stress, and post‐translational modifications of Aβ—into a revised model of Alzheimer's disease.
