In addition to the services described above for transplant patients, HLA testing for the following conditions are also performed:

• Platelet transfusion support: Patients with low platelet counts are at risk for serious bleeding complications and are often transfused with platelets from healthy donors. However, patients can sometimes produce antibodies to the HLA molecules expressed on platelets, which reduce the effectiveness of platelet transfusion. HLA typing and antibody detection help physicians choose a platelet donor that will result in increased platelet counts for patients in need.

The laboratory conducts research primarily focused on improving the methods/ techniques for donor selection/screening and also for developing an algorithm for donor selection, with regular publications in national and international peer reviewed journals. The Laboratory staff participates in conferences and education programs thereby fostering greater awareness levels among staff. The research area is broadly focused on the various aspects of Transplant Immunology & Immunogenetics with relation to various hemato-lymphoid and solid organ transplants. The lab also focuses on translational research using molecular, proteomics, etc. techniques in developing Lab-to-Clinic oriented novel assays with implications in the diagnosis and prognosis of transplant patients resulting in better treatment outcomes and patient care. Pharmacogenomics and disease association in relation to HLA is also being explored.

The lab has various ongoing research projects focussed on improving HLA diagnostics as well as exploring adoptive cellular therapies for leukemic patients.

• Molecular studies
The research under this area are:
1. Non HLA genes associated with allogeneic hematopoietic stem cell transplantation This project is aimed at screening Killer immunoglobulin like receptor genes, polymorphisms within the cytokine and chemokine genes, immune reconstitution profile of the patient at baseline and follow up and correlate them with HSCT outcomes
2. Impact of HLA typing resolution on donor selection and transplant outcomes in matched Allogeneic Hematopoietic Stem Cell Transplantation.
   The aim of this project is to evaluate the role of high resolution HLA typing in predicting HSCT outcomes.
3. Interaction of Vitamin D Receptor gene polymorphism with HLA alleles and its correlation with immune modulation affecting graft outcomes and survival in HLA matched sibling allogeneic stem cell transplantation. This study is planned to investigate the relationship between VDR gene polymorphisms, Vit. D levels pre transplantation and the transplant outcomes in HLA matched HSCT.
• Immunotherapy focussed studies
The ex-vivo and in-vivo research on “adoptive cell immunotherapy” like Virus-specific T-cell (VSTs) and NK cell immunotherapy in Allogeneic-HSCT has been a focus of our lab. The projects under this area of research are:
1. Generation and Characterization of third party donor derived AdV, CMV and EBV multivirus specific T cells for therapeutic intervention in patients undergoing Hematopoietic Stem Cell Transplantation
   Through this project we aim to generate multivirus (AdV, CMV, and EBV) specific T cells which could then be scaled up to GMP and infused in leukemic patients who encounter such viral infections.
2. Implications for NK Immunotherapy: Killer Immunoglobulin like receptor-Human Leukocyte Antigen ligand match/mismatch in post cyclophosphamide T cell replete haploidentical/mismatched HSCT outcomes in AML
   This is a proof of concept project where we are aiming to prove the NK cell cytotoxicity based on the KIR receptor-ligand match/mismatch hypothesis. We will also be looking at the KIR profile pre and post HSCT to look at the functional NK cells being reconstituted. This project will serve as a base for scale up to NK immunotherapy.

The lab participated in the following components of the workshop:

1. Population genetics, anthropology and evolution
   For this component, the lab performed high resolution (NGS) HLA typing for 11 loci in 184 unrelated healthy donors from India. A total of 25 novel alleles were observed, which have been added to the IMGT database and have been published in the peer reviewed HLA journal (Impact Factor 9.2)
2. High-resolution KIR in populations
   As part of this component, KIR high resolution typing (NGS) was conducted for the KIR inhibitory genes in 120 unrelated healthy donors from India. This is the first data from Indian population.
