The relation of morphology and affinity maturation in germinal centers [PDF]

arXiv, 2002
The specific morphology of germinal centers is analyzed in the context of the optimization of the humoral immune response. The relevance of dark and light zones for the affinity maturation process is investigated in the framework of a theoretical model for the germinal center reaction.

Cold plasma treatment boosts barley germination and seedling vigor: Insights into soluble sugar, starch, and protein modifications [PDF]

Journal of Cereal Science, Vol. 116, 103852 (2024)
This study investigates the impact of three cold plasma treatments on barley seed germination: direct treatment of dry seeds (DDS), direct treatment of water-soaked seeds (DWS), and indirect treatment of seeds using plasma-activated water (IPAW).

Optimality of mutation and selection in germinal centers [PDF]

, 2010
The population dynamics theory of B cells in a typical germinal center could play an important role in revealing how affinity maturation is achieved. However, the existing models encountered some conflicts with experiments. To resolve these conflicts, we present a coarse-grained model to calculate the B cell population development in affinity ...

Insights on Advances in 3D Bioprinting for Peripheral Nerve Regeneration

Advanced Therapeutics, EarlyView.
Peripheral nerve injury is a common condition due to trauma that significantly impacts the life of the affected individual. This review explores the anatomy, classification, and pathophysiology of peripheral nerve injuries. It also discusses various types of nerve conduits and presents a detailed review of 3D bioprinted nerve conduits used in both in ...

Roles of Kdm6a and Kdm6b in Regulation of Mammalian Neural Regeneration

Advanced Science, EarlyView.
This study reveals that Kdm6a plays key roles in repressing either peripheral nervous system (PNS) or central nervous system (CNS) axon regeneration, whereas Kdm6b is not involved in regulating CNS axon regeneration. Moreover, both demethylases are able to regulate CNS neuronal survival after injury, but with non‐overlapping mechanisms.

Recycling probability and dynamical properties of germinal center reactions [PDF]

J. Theor. Biol. 210(3) 2001, 265-285, 2001
We introduce a new model for the dynamics of centroblasts and centrocytes in a germinal center. The model reduces the germinal center reaction to the elements considered as essential and embeds proliferation of centroblasts, point mutations of the corresponding antibody types represented in a shape space, differentiation to centrocytes, selection with ...

Inhibition of Aberrant Activated Fibroblast‐Like Synoviocytes in Rheumatoid Arthritis by Leishmania Peptide via the Regulation of Fatty Acid Synthesis Metabolism

Advanced Science, EarlyView.
LACK156‐173 is internalized into RA‐FLSs via CAPN2‐mediated endocytosis and inhibits the aggressive phenotype of RA‐FLSs by restoring dysregulated fatty acid synthesis metabolism mediated by overexpressed FASN. The findings suggest that targeting the restoration of fatty acid metabolism could potentially alleviate synovial invasion and joint damage in ...

Modeling the effects of cymene on the distribution of germination and growth of Beauveria bassiana [PDF]

arXiv, 2010
Essential oils have antifungal and antipathogenic effects and therefore are targets in plant pathology research for their potential uses as natural substitutes for inorganic plant pesticides. Beauveria bassiana, an entomopathogenic fungus, can endophytically colonize a vast number of plant species and trigger induced systemic resistance against plant ...
