Optimal Allocation of Gold Standard Testing under Constrained Availability: Application to Assessment of HIV Treatment Failure [PDF]

open access: yes, 2020
The World Health Organization (WHO) guidelines for monitoring the effectiveness of HIV treatment in resource-limited settings (RLS) are mostly based on clinical and immunological markers (e.g., CD4 cell counts). Recent research indicates that the guidelines are inadequate and can result in high error rates.

Analysis of platelet eluate for the elucidation of sensitization to HLA in kidney transplant candidate

open access: yesActa Scientiarum. Health Sciences, 2015
While a 42-year-old male patient was being prepared for deceased-donor renal transplantation, anti-HLA-A2 antibodies were detected in the serum by enzyme-linked immunosorbent assay (ELISA) method.

Increased Natural Killer Cell Activation in HIV-Infected Immunologic Non-Responders Correlates with CD4+ T Cell Recovery after Antiretroviral Therapy and Viral Suppression

open access: yesPLoS ONE, 2017
The role of natural killer (NK) cell function in HIV disease especially in the setting of long-term antiretroviral therapy (ART) and viral suppression is not fully understood.

The Achilles' Heel of Pancreatic Cancer: Targeting pancreatic cancer's unique immunologic characteristics and metabolic dependencies in clinical trials.

open access: yesJournal of Pancreatology, 2020
Pancreatic ductal adenocarcinoma (PDAC) has a high mortality rate and is notoriously refractory to multiple cancer treatments. In recent years, cancer therapy has expanded beyond traditional cytotoxic chemotherapy to targeted agents and immunotherapy ...

Bayesian Models and Decision Algorithms for Complex Early Phase Clinical Trials [PDF]

open access: yesStatistical Science 2010, Vol. 25, No. 2, 227-244, 2010
An early phase clinical trial is the first step in evaluating the effects in humans of a potential new anti-disease agent or combination of agents. Usually called "phase I" or "phase I/II" trials, these experiments typically have the nominal scientific goal of determining an acceptable dose, most often based on adverse event probabilities.

Targeting of T Lymphocytes to Melanoma Cells Through Chimeric Anti-GD3 Immunoglobulin T-Cell Receptors

open access: yesNeoplasia: An International Journal for Oncology Research, 2000
Immunoglobulin T-cell receptors (IgTCRs) combine the specificity of antibodies with the potency of cellular killing by grafting antibody recognition domains onto TCR signaling chains.

Search and capture efficiency of dynamic microtubules for centrosome relocation during IS formation [PDF]

open access: yesBiophysical Journal (2019), 2019
Upon contact with antigen presenting cells (APCs) cytotoxic T lymphocytes (T cells) establish a highly organized contact zone denoted as immunological synapse (IS). The formation of the IS implies relocation of the microtubule organizing center (MTOC) towards the contact zone, which necessitates a proper connection between MTOC and IS via dynamic ...

Smooth and probabilistic PARAFAC model with auxiliary covariates [PDF]

open access: yesarXiv, 2021
In immunological and clinical studies, matrix-valued time-series data clustering is increasingly popular. Researchers are interested in finding low-dimensional embedding of subjects based on potentially high-dimensional longitudinal features and investigating relationships between static clinical covariates and the embedding.

Functional Attributes of Antibodies, Effector Cells, and Target Cells Affecting NK Cell–Mediated Antibody-Dependent Cellular Cytotoxicity

open access: yesJournal of Immunology, 2019
Key Points IgG fucosylation status and target cell Ag density determine NK cell ADCC. Aspecific serum IgG bound to FcγRIIIa and target cell glycocalyx limit NK cell ADCC. NK cell FcγRIIIa is preferentially occupied by high-affinity afucosylated serum IgG.
