Abstract
It is known that certain human leukocyte antigen (HLA) genes are associated with autoimmune central nervous system (CNS) diseases, such as multiple sclerosis (MS), but their exact role in disease susceptibility and etiopathogenesis remains unclear. The best studied HLA-associated autoimmune CNS disease is MS, and thus will be the primary focus of this review. Other HLA-associated autoimmune CNS diseases, such as autoimmune encephalitis and neuromyelitis optica will be discussed. The lack of animal models to accurately capture the complex human autoimmune response remains a major challenge. HLA transgenic (tg) mice provide researchers with powerful tools to investigate the underlying mechanisms promoting susceptibility and progression of HLA-associated autoimmune CNS diseases, as well as for elucidating the myelin epitopes potentially targeted by T cells in autoimmune disease patients. We will discuss the potential role(s) of autoimmune disease-associated HLA alleles in autoimmune CNS diseases and highlight information provided by studies using HLA tg mice to investigate the underlying pathological mechanisms and opportunities to use these models for development of novel therapies.

Abstract
HLA class I (HLA-I) transgenic mice have proven to be useful models for studying human MHC-related immune responses over the last two decades. However, differences in the processing and presentation machinery between humans and mice may have profound effects on HLA-I restricted antigen presentation. In this study, we generated a novel human TAP-LMP (hTAP-LMP) gene cluster transgenic mouse model carrying an intact human TAP complex and two human immunoproteasome LMP subunits, PSMB8/PSMB9. By crossing the hTAP-LMP strain with different HLA-I transgenic mice, we found that the expression levels of human HLA-I molecules, especially the A3 supertype members (e.g., A11 and A33), were remarkably enhanced in corresponding HLA-I/hTAP-LMP transgenic mice. Moreover, we found that humanized processing and presentation machinery increased antigen presentation of HLA-A11-restricted epitopes and promoted the rapid reduction of hepatitis B virus (HBV) infection in HLA-A11/hTAP-LMP mice. Together, our study highlights that HLA-I/hTAP-LMP mice are an improved model for studying antigen presentation of HLA-I molecules and their related CTL responses.

Abstract
A cosmid clone bearing an HLA class I gene has been isolated from a human genomic library by hybridization to a class I-specific probe. This clone encodes the HLA-A26 molecule characterized by immunologic reagents on murine transfected L cells. Nucleotide sequencing of the A26 allele has been performed, and the deduced amino acid sequence was compared with previously published HLA class I sequences. Amino acid sequence homologies between HLA-A26 molecules and members of the HLA-AW19 cross-reactive group were observed and allowed us to demonstrate that residue Q144 is the only critical residue involved in the binding of the 4E monoclonal antibody defining an epitope common to all HLA-B, -C, and -Aw19 alleles. This study also permitted designation of a V residue at position 189 in the third domain as possibly involved in the binding of the B1-23-2 monoclonal antibody. Furthermore, we located clusters of variability in reference to the three-dimensional structure of the HLA-A molecules, i.e., the ninth residue of the first beta-strand domain, the upper surface of the first helical region, and both beta and alpha structures of the alpha 2 domain.

Abstract
The human major histocompatibility complex is a multigene family containing at least 20 class I genes. Included within this family are the loci encoding the highly polymorphic HLA-A, -B, and -C antigens present at the surface of most nucleated cells. The large number of genes detected with class I probes by Southern blot analysis and the existence of serological reagents defining nonubiquitous, non-HLA-A,B,C class I antigens suggest that products other than HLA-A,B,C antigens are encoded within the class I gene family. These products might be the human counterparts of the murine Qa and TL antigens. In order to identify non-HLA-A,B,C genes, we have developed a probe, JF11, located in noncoding regions flanking the HLA-A locus. This probe detects only a limited number of class I genes and does not detect HLA-A,B,C-associated restriction fragments on Southern blots. This probe was used to screen a human cosmid library. Some of the cosmids isolated with this probe were then transferred into mouse fibroblasts expressing human beta 2-microglobulin. One of the transfectants specifically reacts with one alloantiserum (HA2) that detects HLA class I molecules specific to HLA-A2-positive, phytohemagglutinin-activated T cells and not found on resting T or B cells. Data presented in this paper provide evidence for the isolation and expression of a class I gene encoding a nonubiquitous class I antigen that could be a human analogue of the murine Qa antigens.

Abstract
The human class I alleles HLA-A11 and HLA-A3 have a well-documented history of serological cross-reactivity. This cross-reactivity suggests that they are closely related, a suggestion which is supported by the fact that the HLA-A11 and HLA-A3 genes are distinguished from all other A-locus genes by a restriction fragment length polymorphism observed in Bam HI digests. To examine the extent of sequence homology between HLA-A11 and HLA-A3, we have cloned the HLA-A11 gene and sequenced the coding regions (exons). The results reveal that HLA-A11 and HLA-A3 display the highest degree of homology reported for any pair of serologically defined class I alleles. Only nine base differences resulting in six amino acid differences were observed in exons 2-8. One of the amino acid substitutions is in the alpha 1 domain and the other five are in the alpha 2 domain. comparison of this sequence with that of other human class I molecules implicates Gln62 as a critical residue involved in HLA-A11 - HLA-A3 serological cross-reactivity. In addition, the amino acid sequence allowed us to successfully predict cross-reactive recognition of HLA-A11 by cytotoxic T lymphocytes specific for a rare subtype of HLA-A3, HLA-A3.2. This result provides further support for the importance of the alpha 2 domain residues 152 and 156 in forming determinants on class I molecules that are recognized by cytotoxic T lymphocytes.

Abstract
The lysis by human and murine anti-HLA cytolytic T lymphocytes (CTL) of murine cells expressing class I HLA molecule after gene transfection has been studied using two different murine cells: LMTK- and P815-HTR-TK-. Weak but significant HLA-A11-specific lysis was found occasionally with human CTL on the HLA-A11+ L cells. On the contrary, P815-A11 or P815-A2 cells were lysed strongly and specifically by HLA-A11 or HLA-A2-specific human CTL. The T8+T4- phenotype of the effector cells was confirmed and the reaction was inhibited by anti-HLA class I monoclonal antibodies. Despite their higher sensitivity to human CTL, the P815-HLA+ cells did not express higher levels of HLA antigens than L cells, and the presence or the absence of human beta 2 microglobulin was irrelevant. Anti-human LFA-1 antibodies abrogated the lysis of P815-A11+ cells showing that the LFA-1 receptor which is apparently lacking on the L cell surface was on the contrary expressed on P815 cells. On the other hand, murine anti-HLA CTL have been prepared by immunizing mice against syngeneic HLA-A11+ L cells. They lysed very efficiently and specifically these cells, but appeared completely devoid of activity against human HLA-A11 target cells. This barrier was apparently due to the H-2 restriction of these H-2k anti-HLA murine CTL, as shown by their inability to lyse allogeneic H-2d cells expressing HLA-A11, and by the blocking of their activity by anti H-2k antibodies. By contrast, xenogeneic anti-HLA CTL obtained by immunizing murine lymphocytes against human cells lysed both human and murine HLA+ cells but they reacted with a monomorphic epitope of the HLA molecule in a nonrestricted way. These results show that human cells lyse very efficiently P815 murine cells expressing HLA class I antigens; the higher sensitivity of P815 cells compared to L cells is probably due to the presence of a LFA-1 receptor on these cells; a class I molecule of human origin can be seen as an H-2-restricted minor histocompatibility antigen in another species.
