Moss Extracts as Natural Neuroprotective Agents: Mitigating LPS-Induced Neuroinflammation and Microglial Activation.

Neuroinflammation plays a central role in the pathogenesis of neurodegenerative diseases, and there is increasing interest in identifying natural compounds with anti-neuroinflammatory and neuroprotective effects. In this study, we aimed to investigate the biological activities of ethanol and ethyl acetate extracts from five moss species (, , , , and ) with a focus on their neuroprotective and anti-neuroinflammatory potential. Phytochemical profiling revealed the presence of phenols (up to 24.

Different Genotypes of the Rare and Threatened Moss (Funariaceae) Exhibit Different Resilience to Zinc and Copper Stress.

The funarioid moss species , which is threatened with extinction, was the subject of this study. The riparian habitat type of this species is often under the influence of contaminated water, and, therefore, we tested the influence of selected potentially toxic elements (PTEs), namely zinc and copper, on the development, physiological features, and survival of the species on two different accessions (German and Croatian). The results obtained showed the different resilience of the two accessions to the PTEs.

Sex determination in bryophytes: current state of the art.

With the advent of genomic and other omics technologies, the last decades have witnessed a series of steady and important breakthroughs in the understanding of genetic determinants of different reproductive systems in vascular plants and especially on how sexual reproduction shaped their evolution. In contrast, the molecular mechanisms of these fundamental aspects of the biology of bryophytes, a group of non-vascular embryophyte plants sister to all tracheophytes, are still largely obscure. The recent characterization of the sex chromosomes and genetic switches determining sex in bryophytes and emerging approaches for molecular sexing of gametophytes hold great promise for elucidation of the evolutionary history as well as the conservation of this species-rich but understudied group of land plants.

Effects of the Salt Stress Duration and Intensity on Developmental and Physiological Features of the Moss .

The two accessions of the polytrichaceous moss species , namely German and Serbian genotypes, were subjected to salt stress, aiming to study the species' developmental and physiological features. Various concentrations of sodium chloride were applied to an axenic culture of the two moss genotypes, and the growth parameters as well as physiological feature changes were followed. As inferred by the morpho-developmental parameters and survival index, the Serbian genotype showed higher resistance to salt stress as compared to the German one.

Effects of Cesium on Physiological Traits of the Catherine's Moss Hedw.

Mosses are proven bioindicators of living environments. It is known that mosses accumulate pollutants from precipitates and, to some lesser extent, from the substrate. In this study, the effects of cesium (Cs) on the physiological traits of acrocarp polytrichaceous Catherine's moss ( Hedw.

Analysis of the Qualitative and Quantitative Content of the Phenolic Compounds of Selected Moss Species under NaCl Stress.

The response to salt stress analysed by quantitative and qualitative analyses in three selected moss species was studied. Non-halophytic funaroid and two halophytic mosses, funaroid and pottioid were exposed to salt stress under controlled in vitro conditions. The results clearly showed various phenolics to be present and included to some extent as a non-enzymatic component of oxidative, i.

The Conservation Physiology of Bryophytes.

An introduction to the conservation physiology of bryophytes is given. The insights into the problems, solutions and examples of the physiological approach to conservation within bryophyte representatives are discussed. The significance of experimental treatments of bryophytes is highlighted.

The Influence of Seasonality on Secondary Metabolite Profiles and Neuroprotective Activities of Moss Extracts: In Vitro and In Silico Study.

Numerous representatives of mosses, including , have been used to alleviate different inflammation-related conditions. However, the mode of action underlying this anti-inflammatory potential has been poorly understood. Moreover, the influence of seasonality on the chemical composition and biological activity of mosses is generally overlooked.

Chemical characterization and in vitro immunomodulatory effects of different extracts of moss Hedwigia ciliata (Hedw.) P. Beauv. from the Vršačke Planine Mts., Serbia.

Bioactive compounds from natural sources are of great importance because of their potential pharmacological activity and tremendous structural diversity. In this study, the chemical composition of different moss extracts of Hedwigia ciliata P. Beauv.

Extracts Characterization and In Vitro Evaluation of Potential Immunomodulatory Activities of the Moss Hedw.

Recently, there has been an increasing interest in the chemistry and biological potential of mosses, since a large number of biologically active compounds have been found within these species. This study aimed at examining the chemical composition and immunomodulatory potential (antioxidant, antidiabetic, anti-neuroinflammatory/antineurodegenerative, and antitumor activities) of moss Hedw. extracts.

Metal accumulation in the acrocarp moss Atrichum undulatum under controlled conditions.

Mosses are frequently used to monitor atmospheric metal contamination but few studies on metal adsorption under controlled conditions are available. Here, the accumulation of the heavy metals copper and zinc was studied in the acrocarp moss Atrichum undulatum. An in vitro culture of A.

Is the Binding Pattern of Zinc(II) Equal in Different Bryophyte Species?

Bryophytes are usually taken as good bioindicators. However, they represent a large group of terrestrial plants and they express an enormous range of peculiarities within the plant kingdom. With the aim to search for a common pattern of zinc binding, we established axenical in vitro cultures of a dozen bryophyte species that include hornworts, thallose, and leafy liverworts, as well as acrocarp and pleurocarp mosses.
