Context: Disease Modifying Anti-Rheumatic Drugs (DMARDs) are aimed to interfere rheumatoid arthritis (RA) progression and reduce the joint damage; however, not all patients respond likewise. Killer-cell Immunoglobulin-like Receptors (KIR) and their ligands, Human Leucocyte Antigen class I (HLA-I), have been associated with RA pathology; therefore,...

Killer immunoglobulin-like receptors (KIR) are transmembrane proteins that regulate NK and T cell subsets by recognizing HLA-I molecules as ligands. The KIR gene family consists of 16 genes, located at chromosome 19q13.4. KIR gene frequencies vary among populations. In Mexico, HLA and genetic ancestry studies show that Mestizo populations have diff...

NK and some T cell functions are regulated by the interaction between KIR and HLA molecules. Several studies have shown an association between activating KIR genes and the development of autoimmune diseases, including psoriasis vulgaris (PsV). Our objective was to determine the association between KIR/HLA genes and genotypes with PsV in the Western...

We modified a Sabin Oral Poliovirus Vaccine (OPV) vector to permit secretion of the antigens of interest with the goal of improving anti-HIV Env humoral responses in a SHIV mucosal immunization composed of DNA and recombinant OPVs. We evaluated stimulation of systemic and mucosal cell-mediated and humoral immunity in Rhesus macaques by two regimens...

Mycobacterium tuberculosis (Mtb) continues to define new paradigms of host-pathogen interaction. There are several host proteins known which are regulated by Mtb infection. The proteins which regulate host biological processes like apoptosis, cell processes, stress proteins, metabolic enzymes, etc. are targeted by the pathogens. Mtb proteins intera...

Solute carrier (SLC) transporters constitute a vast superfamily of transmembrane proteins tasked with regulating the transport of various substances such as metabolites, nutrients, ions, and drugs across cellular membranes. SLC transporters exhibit coordinated expression patterns across normal tissues, suggesting a tightly regulated regulatory netw...

Rheumatoid arthritis is a clinical autoimmune syndrome that causes joint damage. The positive or negative anti-cyclic citrullinated protein (CCP) antibodies serodiagnosis differentiates two subsets of the disease, each with different genetic background. Previous studies have identified associations between KIR genes and rheumatoid arthritis but not...

Background: Disease Modifying Antirheumatic Drugs (DMARDs) are designed to interfere in progression of rheumatoid arthritis (RA) and reduce the damage in joints in patients. However, patients do not respond similarly. KIR receptors and their ligands HLA have been associated with RA pathology; therefore, KIR and HLA genes may influence the response...

Patients with leprosy may be affected psychologically and socially by the negative attitude of society toward leprosy, caused by widespread ignorance and prevailing stereotypes surrounding the disease. This study aimed to determine the knowledge and attitudes toward leprosy among students at the University of Guadalajara. This descriptive cross-sec...
