Dendritic cells are cells specialized for antigen capture, migration and T cell stimulation. Recent advances have been made in understanding their origin, their heterogeneity, the mechanism of antigen uptake, and the signals that induce their migration and maturation into immunostimulatory antigen-presenting cells. Dendritic cells represent the natural adjuvants for T cell responses and their t...

Conventional serum antibody titer, which expresses level, does not provide antigen binding avidity of the variable region antibody, is essential for defense response to infection. Here, we quantified anti-SARS-CoV-2 receptor-binding domain (RBD) by competitive binding-inhibition activity (IC50) between SARS-CoV-2 S1 immobilized on DCP microarray and various RBD doses added expressed as 1/IC50 n...

Abstract Immune cells acquire a variety of defects that accumulate overtime in process known as Immunosenescence. To study any innate B lymphocytes may during aging, we have developed an adoptive transfer system using follicular from young (FO Y, 8–12 weeks) and old O, >22 mo.) mice into μMT cell-deficient mouse. This model reveals FO Ocells, compared to their counterparts, produce highe...

background & objectives:  cd10 is a cell surface enzyme with metalloendopeptidase activity, also known as common acute lymphoblastic leukaemia antigen, which mainly serves as a marker for acute lymphoblastic leukemia (all). to date and to the best of our knowledge, only few comparative immunohistochemical studies have assessed cd10 expression in cutaneous epithelial neoplasms. our goal was ...

background:non-melanoma skin cancer (nmsc), the most prevalent types being squamous cell carcinoma (scc) and basal cell carcinoma (bcc), is the most common type of malignancy in human beings. these neoplasms are more frequent in the elderly and fair skinned people and mainly occur on sun-exposed sites of the body. ultraviolet b (uvb) has a well-known effect in induction and promotion of growth ...

biomolecular behavior of tumor cells has become attractive to investigators. p53 as an oncosuppresor gene has been core of various studies and ki67 is a nuclear protein involved in proliferation process. stopping of onco-suppressor function theoretically allows proliferative system to get out of any control. in this case-control study we evaluated 50 patients with non small cell lung cancer, co...

The maturation of dendritic cells (DCs) allows these antigen-presenting cells to initiate immunity. We pursued this concept in situ by studying the adjuvant action of alpha-galactosylceramide (alphaGalCer) in mice. A single i.v. injection of glycolipid induced the full maturation of splenic DCs, beginning within 4 h. Maturation was manifest by marked increases in costimulator and major histocom...
