Opis:
The aim of the study was to determine immunostimulant properties of chitosan administered alimentary to BALB/c mice. We observed that chitosan feeding effected in activation of cells from the peritoneal cavity. The cells produced less nitric oxide with simultaneous enhanced activity of arginase and higher expression of receptor for IL-4. What is more, chitosan caused increased number of cells expressing MHC class II. The study confirms that chitosan can stimulate immune system what potentially makes it useful candidate for adjuvant.

Opis:
Recurrent respiratory tract infections in children are the most common cause of outpatient visits. Due to the necessity of treatment of chronic, frequent use of antibiotics and the dangers of complications are a major clinical problem. Big hopes are now with the possibility of the use of immunostimulation as prevention of these infections. The paper discusses the most important methods of stimulation of the immune system in children. In the light of previous reports were evaluated effects of this type of therapy.

Opis:
Marine invertebrates depend upon antimicrobial peptides (AMPs) as a major component of innate immunity, as they are rapidly synthesized and diffuse upon pathogen invasion. In this study, we report the identification and characterization of a 11 kDa antimicrobial protein, which we name SSAP (for Scylla serrata antimicrobial protein), from granular hemocytes of the mangrove crab S. serrata. The protein is highly similar to scygonadin, a male-specific AMP isolated from the ejaculatory duct of S. serrata. SSAP was isolated using various chromatographic techniques, viz. ion-exchange, ultra filtration and RP-HPLC, and demonstrated antibacterial activity against Gram positive and Gram negative bacteria. Full length mRNA encoding SSAP was amplified using a combination of RT-PCR and RACE. The nucleotide sequence revealed a full-length ORF of 381 bp coding for a preprotein of 126 amino acids comprising a signal peptide of 24 amino acids and a mature protein of 102 amino acids with a predicted mass of 11435 Da and pI of 5.70. Unlike scygonadin, SSAP is expressed in several tissues of both male and female crabs, as evidenced by RT-PCR, Northern and Western blot analyses. The study suggests that SSAP might be an isoform or a variant of scygonadin and might play an important role in regulating the immunity of the crab upon microbial infection.
