Dynamics of cytokines and immunoglobulins serum profiles in primary and secondary Cryptosporidium parvum infection: Usefulness of Luminex® xMAP technology

Infection by Cryptosporidium parvum triggers a complex array of innate and adaptive cell mediated immune response, playing an important role in controlling the infection. To date, there are no studies applying the Luminex® xMAP technology to determine profiles of cytokines and immunoglobulins in the context of an infection by C. parvum. In this study, we analyzed these immune mediators in the serum of immunocompetent mice inoculated with C. parvum oocysts, using Luminex, to understand how the immune system responds to an infection by this parasite.

Application of hyperthermia for cancer treatment: recent patents review.

Cancer is one of the main causes of death in the world and its incidence increases every day. Current treatments are insufficient and present many breaches. Hyperthermia is an old concept and since early it was established as a cancer treatment option, mainly in superficial cancers.

Monoclonal antibody technology applied to the detection of Cryptosporidium parvum oocysts in human and cattle fecal samples

With the discovery that the coccidian parasiteCryptosporidium sp. can cause severe symptoms in humans, many diagnostic techniques were quickly implemented such as microscopic visualization, immunofluorescence and PCR. Currently, there is no effective drug treatment and none of the current diagnostic methods is 100% accurate. In this study, a BALB/C mouse was subcutaneously immunized with Cryptosporidium parvum oocysts extract.

Protein Disulfide Isomerases: Impact of Thapsigargin treatment on their expression in melanoma cell lines

Anti-cancer treatments usually elevate the content of unfolded or misfolded proteins in the endoplasmic reticulum (ER). Here we aimed to get insights into the relation between sensitivity of melanoma cell lines to the ER stress inducer thapsigargin (THG) and the genetic expression of protein disulfide isomerase family members (PDIs). The expression of PDIs was analysed […]

Challenges in Antibody Development against Tn and Sialyl-Tn Antigens

The carbohydrate antigens Tn and sialyl-Tn (STn) are expressed in most carcinomas and usually absent in healthy tissues. These antigens have been correlated with cancer progression and poor prognosis, and associated with immunosuppressive microenvironment. Presently they are used in clinical trials as therapeutic vaccination, but with limited success due to their low immunogenicity. Alternatively, anti-Tn […]
